    _category.description
;    Data items in the ARRAY_DATA category are the containers for
     the array data items described in the category ARRAY_STRUCTURE.
    
     It is recognized that the data in this category needs to be used in
     two distinct ways.  During a data collection the lack of ancillary
     data and timing constraints in processing data may dictate the
     need to make a 'miniCBF' nothing more than an essential minimum
     of information to record the results of the data collection.  In that
     case it is proper to use the ARRAY_DATA category as a
     container for just a single image and a compacted, beam-line
     dependent list of data collection parameter values.  In such
     a case, only the tags '_array_data.header_convention',
     '_array_data.header_contents' and '_array_data.data' need be
     populated.
    
     For full processing and archiving, most of the tags in this
     dictionary will need to be populated.

        Example 1 -

        This example shows two binary data blocks.  The first one
        was compressed by the CBF_CANONICAL compression algorithm and is
        presented as hexadecimal data.  The first character 'H' on the
        data lines means hexadecimal.  It could have been 'O' for octal
        or 'D' for decimal.  The second character on the line shows
        the number of bytes in each word (in this case '4'), which then
        requires eight hexadecimal digits per word.  The third character
        gives the order of octets within a word, in this case '<'
        for the ordering 4321 (i.e. 'big-endian').  Alternatively, the
        character '>' could have been used for the ordering 1234
        (i.e. 'little-endian').  The block has a 'message digest'
        to check the integrity of the data.

        The second block is similar, but uses CBF_PACKED compression
        and BASE64 encoding.  Note that the size and the digest are
        different.

    _item_description.description
;             The value of _array_data.data contains the array data
              encapsulated in a STAR string.

              The representation used is a variant on the
              Multipurpose Internet Mail Extensions (MIME) specified
              in RFC 2045-2049 by N. Freed et al.  The boundary
              delimiter used in writing an imgCIF or CBF is
              '\n--CIF-BINARY-FORMAT-SECTION--' (including the
              required initial '\n--').

              The Content-Type may be any of the discrete types permitted
              in RFC 2045; 'application/octet-stream' is recommended
              for diffraction images in the ARRAY_DATA category.
              Note:  When appropriate in other categories, e.g. for
              photographs of crystals, more precise types, such as
              'image/jpeg', 'image/tiff', 'image/png', etc. should be used.
             
              If an octet stream was compressed, the compression should
              be specified by the parameter
                'conversions="X-CBF_PACKED"'
              or the parameter
                'conversions="X-CBF_CANONICAL"'
              or the parameter
                'conversions="X-CBF_BYTE_OFFSET"'
              or the parameter
                'conversions="X-CBF_BACKGROUND_OFFSET_DELTA"'
               
              If the parameter
                'conversions="X-CBF_PACKED"'
              is given it may be further modified with the parameters
                '"uncorrelated_sections"'
              or
                '"flat"'
             
              If the '"uncorrelated_sections"' parameter is
              given, each section will be compressed without using
              the prior section for averaging.
             
              If the '"flat"' parameter is given, each the
              image will be treated as one long row.
             
              Note that the X-CBF_CANONICAL and X-CBF_PACKED are
              slower but more efficient compressions that the others.
              The X-CBF_BYTE_OFFSET compression is a good compromise
              between speed and efficiency for ordinary diffraction
              images.  The X-CBF_BACKGROUND_OFFSET_DELTA compression
              is oriented towards sparse data, such as masks and
              tables of replacement pixel values for images with
              overloaded spots.

              The Content-Transfer-Encoding may be 'BASE64',
              'Quoted-Printable', 'X-BASE8', 'X-BASE10',
              'X-BASE16' or 'X-BASE32K', for an imgCIF or 'BINARY'
              for a CBF.  The octal, decimal and hexadecimal transfer
              encodings are provided for convenience in debugging and
              are not recommended for archiving and data interchange.

              In a CIF, one of the parameters 'charset=us-ascii',
              'charset=utf-8' or 'charset=utf-16' may be used on the
              Content-Transfer-Encoding to specify the character set
              used for the external presentation of the encoded data.
              If no charset parameter is given, the character set of
              the enclosing CIF is assumed.  In any case, if a BOM
              flag is detected (FE FF for big-endian UTF-16, FF FE for
              little-endian UTF-16 or EF BB BF for UTF-8) is detected,
              the indicated charset will be assumed until the end of the
              encoded data or the detection of a different BOM.  The
              charset of the Content-Transfer-Encoding is not the character
              set of the encoded data, only the character set of the
              presentation of the encoded data and should be respecified
              for each distinct STAR string.

              In an imgCIF file, the encoded binary data begins after
              the empty line terminating the header.  In an imgCIF file,
              the encoded binary data ends with the terminating boundary
              delimiter '\n--CIF-BINARY-FORMAT-SECTION----'
              in the currently effective charset or with the '\n; '
              that terminates the STAR string.

              In a CBF, the raw binary data begins after an empty line
              terminating the header and after the sequence:

              Octet   Hex   Decimal  Purpose
                0     0C       12    (ctrl-L) Page break
                1     1A       26    (ctrl-Z) Stop listings in MS-DOS
                2     04       04    (Ctrl-D) Stop listings in UNIX
                3     D5      213    Binary section begins

              None of these octets are included in the calculation of
              the message size or in the calculation of the
              message digest.

              The X-Binary-Size header specifies the size of the
              equivalent binary data in octets.  If compression was
              used, this size is the size after compression, including
              any book-keeping fields.  An adjustment is made for
              the deprecated binary formats in which eight bytes of binary
              header are used for the compression type.  In this case,
              the eight bytes used for the compression type are subtracted
              from the size, so that the same size will be reported
              if the compression type is supplied in the MIME header.
              Use of the MIME header is the recommended way to
              supply the compression type.  In general, no portion of
              the  binary header is included in the calculation of the size.

              The X-Binary-Element-Type header specifies the type of
              binary data in the octets, using the same descriptive
              phrases as in _array_structure.encoding_type.  The default
              value is 'unsigned 32-bit integer'.

              An MD5 message digest may, optionally, be used. The 'RSA Data
              Security, Inc. MD5 Message-Digest Algorithm' should be used.
              No portion of the header is included in the calculation of the
              message digest.

              If the Transfer Encoding is 'X-BASE8', 'X-BASE10' or
              'X-BASE16', the data are presented as octal, decimal or
              hexadecimal data organized into lines or words.  Each word
              is created by composing octets of data in fixed groups of
              2, 3, 4, 6 or 8 octets, either in the order ...4321 ('big-
              endian') or 1234... ('little-endian').  If there are fewer
              than the specified number of octets to fill the last word,
              then the missing octets are presented as '==' for each
              missing octet.  Exactly two equal signs are used for each
              missing octet even for octal and decimal encoding.
              The format of lines is:

              rnd xxxxxx xxxxxx xxxxxx

              where r is 'H', 'O' or 'D' for hexadecimal, octal or
              decimal, n is the number of octets per word and d is '<'
              or '>' for the '...4321' and '1234...' octet orderings,
              respectively.  The '==' padding for the last word should
              be on the appropriate side to correspond to the missing
              octets, e.g.

              H4< FFFFFFFF FFFFFFFF 07FFFFFF ====0000

              or

              H3> FF0700 00====

              For these hexadecimal, octal and decimal formats only,

              BASE64 encoding follows MIME conventions.  Octets are
              in groups of three: c1, c2, c3.  The resulting 24 bits
              are broken into four six-bit quantities, starting with
              the high-order six bits (c1 >> 2) of the first octet, then
              the low-order two bits of the first octet followed by the
              high-order four bits of the second octet [(c1 & 3)<<4 | (c2>>4)],
              then the bottom four bits of the second octet followed by the
              high-order two bits of the last octet [(c2 & 15)<<2 | (c3>>6)],
              then the bottom six bits of the last octet (c3 & 63).  Each
              of these four quantities is translated into an ASCII character
              using the mapping:

                        1         2         3         4         5         6
              0123456789012345678901234567890123456789012345678901234567890123
              |         |         |         |         |         |         |
              ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/

              With short groups of octets padded on the right with one '='
              if c3 is missing, and with '==' if both c2 and c3 are missing.

              X-BASE32K encoding is similar to BASE64 encoding, except that
              sets of 15 octets are encoded as sets of 8 16-bit unicode
              characters, by breaking the 120 bits into 8 15-bit quantities.
              256 is added to each 15 bit quantity to bring it into a
              printable uncode range.  When encoding, zero padding is used
              to fill out the last 15 bit quantity.  If 8 or more bits of
              padding are used, a single equals sign (hexadecimal 003D) is
              appended.  Embedded whitespace and newlines are introduced
              to produce lines of no more than 80 characters each.  On
              decoding, all printable ascii characters and ascii whitespace
              characters are ignored except for any trailing equals signs.
              The number of trailing equals signs indicated the number of
              trailing octets to be trimmed from the end of the decoded data.
              (see Georgi Darakev, Vassil Litchev, Kostadin Z. Mitev, Herbert
              J. Bernstein, 'Efficient Support of Binary Data in the XML
              Implementation of the NeXus File Format',absract W0165,
              ACA Summer Meeting, Honolulu, HI, July 2006).

              QUOTED-PRINTABLE encoding also follows MIME conventions, copying
              octets without translation if their ASCII values are 32...38,
              42, 48...57, 59, 60, 62, 64...126 and the octet is not a ';'
              in column 1.  All other characters are translated to =nn, where
              nn is the hexadecimal encoding of the octet.  All lines are
              'wrapped' with a terminating '=' (i.e. the MIME conventions
              for an implicit line terminator are never used).
             
              The "X-Binary-Element-Byte-Order" can specify either
              '"BIG_ENDIAN"' or '"LITTLE_ENDIAN"' byte order of the imaage
              data.  Only LITTLE_ENDIAN is recommended.  Processors
              may treat BIG_ENDIAN as a warning of data that can
              only be processed by special software.

              The "X-Binary-Number-of-Elements" specifies the number of
              elements (not the number of octets) in the decompressed, decoded
              image.

              The optional "X-Binary-Size-Fastest-Dimension" specifies the
              number of elements (not the number of octets) in one row of the
              fastest changing dimension of the binary data array. This
              information must be in the MIME header for proper operation of
              some of the decompression algorithms.

              The optional "X-Binary-Size-Second-Dimension" specifies the
              number of elements (not the number of octets) in one column of
              the second-fastest changing dimension of the binary data array.
              This information must be in the MIME header for proper operation
              of some of the decompression algorithms.

              The optional "X-Binary-Size-Third-Dimension" specifies the
              number of sections for the third-fastest changing dimension of
              the binary data array.
             
              The optional "X-Binary-Size-Padding" specifies the size in
              octets of an optional padding after the binary array data and
              before the closing flags for a binary section.

              The detector may have a complex relationship
              between the raw intensity values and the number of
              incident photons.  In most cases, the number stored

              to the actual number of incident photons, given by
              _array_intensities.gain.  If raw, uncorrected values
              are presented (e.g. for calibration experiments), the
              value of _array_intensities.linearity will be 'raw'
              and _array_intensities.gain will not be used.

    The argument has been made that these attributes are not needed
    because NeXus files are supposed to have "true values" stored.
    In many cases that is true and then none of these attributes
    are needed.  However, with some detectors and some experiments
    there are good technical and scientific reasons to bring in values
    that will need processing later to derive "true values", and in
    those case some or all of these attributes will be needed.  They
    are provided for such cases.
   
    The same attributes could be used as fields in the case of a single
    data array, but in that case links for all the fields would be needed
    from NXdata to NXdetector, so it is preferable to use attributes even
    in the case of a single data array.  The reverse mapping will support
    both uses.

    _item_description.description
;              The intensity linearity scaling method used to convert
               from the raw intensity to the stored element value:

               'linear' is linear.

               'offset'  means that the value defined by
               _array_intensities.offset should be added to each
                element value.

               'scaling' means that the value defined by
               _array_intensities.scaling should be multiplied with each
               element value.

               'scaling_offset' is the combination of the two previous cases,
               with the scale factor applied before the offset value.

               'sqrt_scaled' means that the square root of raw
               intensities multiplied by _array_intensities.scaling is
               calculated and stored, perhaps rounded to the nearest
               integer. Thus, linearization involves dividing the stored
               values by _array_intensities.scaling and squaring the
               result.

               'logarithmic_scaled' means that the logarithm base 10 of
               raw intensities multiplied by _array_intensities.scaling
               is calculated and stored, perhaps rounded to the nearest
               integer. Thus, linearization involves dividing the stored
               values by _array_intensities.scaling and calculating 10
               to the power of this number.

               'raw' means that the data are a set of raw values straight
               from the detector.

               reported.  This value is intended for use either in

               This data item is related to the axes of the detector
               itself given in DIFFRN_DETECTOR_AXIS, but usually differs
               in that the axes in this category are the axes of the

               DIFFRN_DETECTOR_AXIS are the physical axes
               of the detector describing the 'poise' of the detector as an
               overall physical object.

               If there is only one axis in the set, the identifier of
               that axis should be used as the identifier of the set.

save_array_structure_list_section
    _category.description
;    Data items in the ARRAY_STRUCTURE_LIST_SECTION category identify
     the dimension-by-dimension start, end and stride of each section of an
     array that is to be referenced.
   
     For any array of array_id, ARRAYID, array section ids of the form
     ARRAYID(start1:end1:stride1,start2:end2:stride2, ...) are defined
     by default.
   
     For the given index, the elements in
     the section are of indices:  _array_structure_list_section.start,
       _array_structure_list_section.start
         +_array_structure_list_section.stride,
       _array_structure_list_section.start
        +2*_array_structure_list_section.stride,
       ...
     stopping either when the indices leave the limits of the indices of that dimension
     or [min(_array_structure_list_section.start,
     _array_structure_list_section.end),
     max(_array_structure_list_section.start,
     _array_structure_list_section.end)].
   
   
     The ordering of these elements is determined by the overall ordering of
     _array_structure_list_section.array_id and not by the ordering implied by the
     stride.

save_array_structure_list_axis
    _category.description
;    Data items in the ARRAY_STRUCTURE_LIST_AXIS category describe
     the physical settings of sets of axes for the centres of pixels that
     correspond to data points described in the
     ARRAY_STRUCTURE_LIST category.

     In the simplest cases, the physical increments of a single axis correspond
     to the increments of a single array index.  More complex organizations,
     e.g. spiral scans, may require coupled motions along multiple axes.

     Note that a spiral scan uses two coupled axes: one for the angular
     direction and one for the radial direction.  This differs from a
     cylindrical scan for which the two axes are not coupled into one
     set.
   
     Axes may be specified wither for an entire array or for just a section
     of an array.

    _category.description
;    Data items in the AXIS category record the information required
     to describe the various goniometer, detector, source and other
     axes needed to specify a data collection or the axes defining the
     coordinate system of an image. 
    
     The location of each axis is specified by two vectors: the axis
     itself, given by a  unit vector in the direction of the axis, and
     an offset to the base of the unit vector. 
    
     The vectors defining an axis are referenced to an appropriate
     coordinate system.  The axis vector, itself, is a dimensionless
     unit vector.  Where meaningful, the offset vector is given in
     millimetres.  In coordinate systems not measured in metres,
     the offset is not specified and is taken as zero.
    
     The available coordinate systems are:
    
         The imgCIF standard laboratory coordinate system
         The direct lattice (fractional atomic coordinates)
         The orthogonal Cartesian coordinate system (real space)
         The reciprocal lattice
         An abstract orthogonal Cartesian coordinate frame
     
     For consistency in this discussion, we call the three coordinate
     system axes X, Y and Z.  This is appropriate for the imgCIF
     standard laboratory coordinate system, and last two Cartesian
     coordinate systems, but for the direct lattice, X corresponds
     to a, Y to b and Z to c, while for the reciprocal lattice,
     X corresponds to a*, Y to b* and Z to c*.
    
     For purposes of visualization, all the coordinate systems are
     taken as right-handed, i.e., using the convention that the extended
     thumb of a right hand could point along the first (X) axis, the
     straightened pointer finger could point along the second (Y) axis
     and the middle finger folded inward could point along the third (Z)
     axis. 
    
     THE IMGCIF STANDARD LABORATORY COORDINATE SYSTEM
    
     The imgCIF standard laboratory coordinate system is a right-handed  
     orthogonal coordinate similar to the MOSFLM coordinate system, 
     but imgCIF puts Z along the X-ray beam, rather than putting X along the
     X-ray beam as in MOSFLM.
    
     The vectors for the imgCIF standard laboratory coordinate system
     form a right-handed Cartesian coordinate system with its origin
     in the sample or specimen.  The origin of the axis system should,
     if possible, be defined in terms of mechanically stable axes to be
     be both in the sample and in the beam.  If the sample goniometer or other
     sample positioner has two axes the intersection of which defines a
     unique point at which the sample should be mounted to be bathed
     by the beam, that will be the origin of the axis system.  If no such
     point is defined, then the midpoint of the line of intersection
     between the sample and the center of the beam will define the origin.
     For this definition the sample positioning system will be set at
     its initial reference position for the experiment.

     Axis 1 (X): The X-axis is aligned to the mechanical axis pointing from
     the sample or specimen along the  principal axis of the goniometer or
     sample positioning system if the sample positioning system has an axis
     that intersects the origin and which form an angle of more than 22.5
     degrees with the beam axis.
    
     Axis 2 (Y): The Y-axis completes an orthogonal right-handed system
     defined by the X-axis and the Z-axis (see below).

     Axis 3 (Z): The Z-axis is derived from the source axis which goes from
     the sample to the source.  The Z-axis is the component of the source axis
     in the direction of the source orthogonal to the X-axis in the plane
     defined by the X-axis and the source axis.

     If the conditions for the X-axis can be met, the coordinate system
     will be based on the goniometer or other sample positioning system
     and the beam and not on the orientation of the detector, gravity etc. 
     The vectors necessary to specify all other axes are given by sets of
     three components in the order (X, Y, Z).
     If the axis involved is a rotation axis, it is right-handed, i.e. as
     one views the object to be rotated from the origin (the tail) of the
     unit vector, the rotation is clockwise.  If a translation axis is
     specified, the direction of the unit vector specifies the sense of
     positive translation.

     Note:  This choice of coordinate system is similar to but significantly
     different from the choice in MOSFLM (Leslie & Powell, 2004).  In MOSFLM,
     X is along the X-ray beam (the CBF/imgCIF Z axis) and Z is along the
     rotation axis.
    
     In some experimental techniques, there is no goniometer or the principal
     axis of the goniometer is at a small acute angle with respect to
     the source axis.  In such cases, other reference axes are needed
     to define a useful coordinate system.  The order of priority in
     defining directions in such cases is to use the detector, then
     gravity, then north.
    
    
     If the X-axis cannot be defined as above, then the
     direction (not the origin) of the X-axis should be parallel to the axis
     of the primary detector element corresponding to the most rapidly
     varying dimension of that detector element's data array, with its
     positive sense corresponding to increasing values of the index for
     that dimension.  If the detector is such that such a direction cannot
     be defined (as with a point detector) or that direction forms an
     angle of less than 22.5 degrees with respect to the source axis, then
     the X-axis should be chosen so that if the Y-axis is chosen
     in the direction of gravity, and the Z-axis is chosen to be along
     the source axis, a right-handed orthogonal coordinate system is chosen. 
     In the case of a vertical source axis, as a last resort, the
     X-axis should be chosen to point North.
    
     All rotations are given in degrees and all translations are given in mm.

     Axes may be dependent on one another.  The X-axis is the only goniometer
     axis the direction of which is strictly connected to the hardware.  All
     other axes are specified by the positions they would assume when the
     axes upon which they depend are at their zero points.

     When specifying detector axes, the axis is given to the beam centre.
     The location of the beam centre on the detector should be given in the
     DIFFRN_DETECTOR category in distortion-corrected millimetres from
     the (0,0) corner of the detector.
   
     For convenience when describing detector element (module) placement,
     and optional mounting rotation axis and rotation angle may be
     specified.  In such cases, the mounting rotation axis and angle
     of rotation around the mounting rotation axis are applied after
     applying the transformations upon which the given axis depends.

     It should be noted that many different origins arise in the definition
     of an experiment.  In particular, as noted above, it is necessary to
     specify the location of the beam centre on the detector in terms
     of the origin of the detector, which is, of course, not coincident
     with the centre of the sample.
    
     The unit cell, reciprocal cell and crystallographic orthogonal
     Cartesian coordinate system are defined by the CELL and the matrices
     in the ATOM_SITES category.
    
     THE DIRECT LATTICE (FRACTIONAL COORDINATES)
    
     The direct lattice coordinate system is a system of fractional
     coordinates aligned to the crystal, rather than to the laboratory.
     This is a natural coordinate system for maps and atomic coordinates.
     It is the simplest coordinate system in which to apply symmetry.
     The axes are determined by the cell edges, and are not necessarily
     othogonal.  This coordinate system is not uniquely defined and
     depends on the cell parameters in the CELL category and the
     settings chosen to index the crystal.
    
     Molecules in a crystal studied by X-ray diffracraction are organized
     into a repeating regular array of unit cells.  Each unit cell is defined
     by three vectors, a, b and c.  To quote from Drenth,
    
    
     "The choice of the unit cell is not unique and therefore, guidelines
     have been established for selecting the standard basis vectors and
     the origin.  They are based on symmetry and metric considerations:
    
      "(1)  The axial system should be right handed.
       (2)  The basis vectors should coincide as much as possible with
       directions of highest symmetry."
       (3)  The cell taken should be the smallest one that satisfies
       condition (2)
       (4)  Of all the lattice vectors, none is shorter than a.
       (5)  Of those not directed along a, none is shorter than b.
       (6)  Of those not lying in the ab plane, none is shorter than c.
       (7)  The three angles between the basis vectors a, b and c are
       either all acute (<90) or all obtuse (>=90)."

     These rules do not produce a unique result that is stable under
     the assumption of experimental errors, and the the resulting cell
     may not be primitive.
    
     In this coordinate system, the vector (.5, .5, .5) is in the middle
     of the given unit cell.
    
     Grid coordinates are an important variation on fractional coordinates
     used when working with maps.  In imgCIF, the conversion from
     fractional to grid coordinates is implicit in the array indexing
     specified by _array_structure_list.dimension.  Note that this
     implicit grid-coordinate scheme is 1-based, not zero-based, i.e.
     the origin of the cell for axes along the cell edges with no
     specified _array_structure_list_axis.displacement will have
     grid coordinates of (1,1,1), i.e. array indices of (1,1,1).
    
     THE ORTHOGONAL CARTESIAN COORDINATE SYSTEM (REAL SPACE)
    
     The orthogonal Cartesian coordinate system is a transformation of
     the direct lattice to the actual physical coordinates of atoms in
     space.  It is similar to the laboratory coordinate system, but
     is anchored to and moves with the crystal, rather than being
     schored to the laboratory.  The transformation from fractional
     to orthogonal cartesian coordinates is given by the
              _atom_sites.Cartn_transf_matrix[i][j]  and
              _atom_sites.Cartn_transf_vector[i]
     tags.  A common choice for the matrix of the transformation is
     given in the 1992 PDB format document
    
              | a      b cos(\g)   c cos(\b)                            |
              | 0      b sin(\g)   c (cos(\a) - cos(\b)cos(\g))/sin(\g) |
              | 0      0           V/(a b sin(\g))                      |
    
     This is a convenient coordinate system in which to do fitting
     of models to maps and in which to understand the chemistry of
     a molecule.
    
     THE RECIPROCAL LATTICE
    
     The reciprocal lattice coordinate system is used for diffraction
     intensitities.  It is based on the reciprocal cell, the dual of the cell,
     in which reciprocal cell edges are derived from direct cell faces:
    
        a* = bc sin(\a)/V  b* = ac sin(\b)/V  c* = ab sin(\g)/V
        cos(\a*) = (cos(\b) cos(\g) - cos(\a))/(sin(\b) sin(\g))
        cos(\b*) = (cos(\a) cos(\g) - cos(\b))/(sin(\a) sin(\g))
        cos(\g*) = (cos(\a) cos(\b) - cos(\g))/(sin(\a) sin(\b))
        V = abc SQRT(1 - cos(\a)^^2^
                       - cos(\b)^^2^
                       - cos(\g)^^2^
                       + 2 cos(\a) cos(\b) cos(\g) )
    
     In this form the dimensions of the reciprocal lattice are in reciprocal
     \%Angstroms (\%A^^-1^).  A dimensionless form can be obtained by
     multiplying by the wavelength.  Reflections are commonly indexed against
     this coordinate system as (h, k, l) triples.

    Differences in Coordinate Frames
   

    The standard coordinate frame in NeXus is the McStas coordinate frame,
    in which the Z-axis points in the direction of the incident beam, the
    X-axis is orthogonal to the Z-axis in the horizontal plane and pointing
    left as seen from the source and the Y-axis points upwards.  The
    origin is in the sample.

    The standard coordinate frame in imgCIF/CBF aligns the X-axis to the
    principal goniometer axis, chooses the Z-axis to point from the sample
    into the beam.  If the beam is not orthogonal to the X-axis, the Z-axis
    is the component of the vector points into the beam orthogonal to the
    X-axis.  The Y-axis is chosen to complete a right-handed axis system.

    Let us call the NeXus coordinate axes, X_nx, Y_nx and Z_nx and the
    imgCIF/CBF coordinate axes, X_cbf, Y_cbf and $Z_cbf and the direction
    of gravity, Gravity.  In order to translate a vector v_nx = ( x, y, z)
    from the NeXus coordinate system to the imgCIF coordinate system, we
    also need two additional axes, as unit vectors, Gravity_cbf the downwards
    direction, and  Beam_cbf, the direction of the beam e.g. ( 0, 0, -1)).  

    In practice, the beam is not necessarily perfectly horizontal, so Y_nx
    is not necessarily perfectly vertical. Therefore, in order to generate
    X_nx, Y_nx and Z_nx some care is needed.  The cross product between two
    vectors a and b is a new vector c orthogonal to both a and b,
    chosen so that a, b, c is a right handed system.  If a and b are
    orthogonal unit vectors, this right-handed system is an orthonormal
    coordinate system.

    In the CBF coordinate frame, Z_nx is aligned to Beam_cbf

        Z_nx = Beam_cbf
   
    X_nx is defined as being horizontal at right angles to the beam,
    pointing to the left when seen from the source.  Assuming the beam is
    not vertical, we can compute X_nx as the normalized cross product of
    the  beam and the gravity:

        X_nx = (Beam_cbf x Gravity_cbf)/||Beam_cbf x Gravity_cbf||

    To see that this satisfies the constraint of being horizontal and
    pointing to the left, consider the case of Beam = ( 0, 0, -1 )
    and Gravity = ( 0, 0, 1 ) then we would have X_nx = ( 1, 0, 0 )
    from the cross product above.  The normalization is only necessary
    if the beam is not horizontal.

    Finally Y_nx is computed as the cross product of the beam and X_nx,
    completing an orthonormal right-handed system with Y_nx pointing upwards

        Y_nx = Beam_cbf x X_nx

    Then we know that in the imgCIF/CBF coordinate frame
   
        v_nx = X.X_nx + Y.Y_nx + Z.Z_nx

    Thus, given the imgCIF/CBF vectors for the true direction of the beam
    and the true direction of gravity, we have a linear transformation from
    the NeXus coordinate frame to the imgCIF/CBF coordinate frame.   The
    origins of the two frames agree.   The inverse linear transformation will
    transform a vector in the imgCIF/CBF coordinate frame into the NeXus
    coordinate frame.

    In the common case in which the beam is orthogonal to the principal
    goniometer axis so that Beam_cbf = ( 0, 0, -1 ) and the imgCIF/CBF
    Y-axis points upwards, the transformation inverts the X and Z axes.
    In the other common case in which the beam is orthogonal to the
    principal goniometer axis and the imgCIF/CBF Y-axis points
    downwards, the transformation inverts the Y and Z axes.
                                         
    mapping Axes

    There are two transformations needed:  coordxform(v) which takes a vector,
    v, the the CBF imgCIF Standard Laboratory Coordinate System and returns the
    equivalent McStas coordinate vector, and offsetxform(o) which takes an
    offset, o, in the the CBF imgCIF Standard Laboratory Coordinate System and
    returns the equivalent NeXus offset.  As of this writing, it has not
    been decided as to whether the NeXus offset should also be relative
    (in which case offsetxform = coordxform) or whether the NeXus offset should
    be absolute.

    In imgCIF/CBF all the information about all axes other than their
    settings are gathered in one AXIS category.  The closest equivalent
    container in NeXus is the NXinstrument class.  We put the information
    about detector axes into a
    detector:NXdetector/tranformations:NXtransformations NeXus class instance,
    information about the goniometer into a
    goniometer:NXgoniometer/tranformations:NXtransformations NeXus
    class instance, etc.  Additionally, in view of the general nature of
    some axes, such as the coordinate frame axes and gravity, we add a
    transformations:NXtransformation NeXus class instance under NXentry with
    axis__gravity, axis__beam and other axes not tied to specific equipment.

    We have applied the coordinate frame transformation changing
    the CBF laboratory coordinates into McStas coordinates.  Notice that X and
    Z have changed direction, but Y has not.   In other experimental setup,
    other transformations may occur.   The offsets for dependent axes are
    given relative to the total offset of axes on which that axis is dependent.
    Note that the axis settings do not enter into this calculation, because the
    offsets of dependent axes are given with all axes at their zero settings


    The cbf_location attribute gives a mapping back into the CBF AXIS category
    in dotted notation.  The first component is the data block.  The second
    component is "axis".  The third component is either "vector" or
    "offset"  for information drawn from the AXIS.VECTOR[...] or
    AXIS.OFFSET[...] respectively.  The last component is the CBF row number
    to facilitate recovering the original CBF layout.

        structure determination. A practical
        guide, 2nd ed. p. 134. New York: Wiley Interscience].

        There are three axes specified, and no offsets.  The outermost axis,
        omega, is pointed along the X axis.  The next innermost axis, kappa,
        is at a 50 degree angle to the X axis, pointed away from the source.
        The innermost axis, phi, aligns with the X axis when omega and
        phi are at their zero points.  If T-omega, T-kappa and T-phi
        are the transformation matrices derived from the axis settings,
        the complete transformation would be:

;       Example 5 -
   
    This example show an excerpt from the axis specification of an FEL detector
    provided by N. Sauter and A. Brewster.
   
    The detector is divided into 4 quadrants, each quadrant contains 8 sensors
    and each sensor contains 2 ASICs.  We want to be able to refine the
    placement of each of these elements, so we maintain the set of vectors
    that places them.

;       Example 6 -
   
    This example show an excerpt from the axis specification of an FEL detector
    provided by N. Sauter and A. Brewster, using _axis.rotation_axis and
    _axis.rotation to organize the positional dependencies.  The approach
    in Example 5 is now preferred.
   
    The detector is divided into 4 quadrants, each quadrant contains 8 sensors
    and each sensor contains 2 ASICs.  We want to be able to refine the
    placement of each of these elements, so we maintain the set of vectors
    that places them.
   
    To do this, the first vector of importance is an initial placement axis
    that moves from the origin along the Z axis a distance equal to the
    detector distance.  This is the origin for the rest of the axes and is
    called AXIS_D0_ORIGIN.
   
    Each subsequent movement involves a frame shift.  This is done by using
    two imageCIF axes: a rotation axis and a translation axis.  The rotation
    axis is listed first, and includes no offset or angle.  The actual frame
    shift is done by using a translation axis.  An offset is used first in
    the parent's frame, and then an angle is listed to rotate around the
    rotation axis.
   
    Example, sensor five of quadrant 2.  First a rotation axis is listed:
   
    AXIS_D0Q2S5_ROT rotation detector AXIS_D0Q2 0.0 0.0 1.0 0 0 0 . .
    This defines a rotation axis around the z-axis in the frame of quadrant 2.
   
    Next a translation axis is listed:
    AXIS_D0Q2S5 translation detector
        AXIS_D0Q2 . . . 34.5494875 -24.1901 0.0 89.68154 AXIS_D0Q2S5_ROT
    Here, in the frame of quadrant 2, we shift X by 34 and Y by -24
    millimeters, then rotate 89 degrees around the axis named AXIS_D0Q2S5_ROT.
   
    And so forth.

               the normal to the polarization plane and the laboratory Y
               axis as defined in the AXIS category.

               Note that this is the angle of polarization of the source
               photons, either directly from a synchrotron beamline or
               from a monochromater.

               This differs from the value of
               _diffrn_radiation.polarisn_norm
               in that _diffrn_radiation.polarisn_norm refers to
               polarization relative to the diffraction plane rather than
               to the laboratory axis system.

               In the case of an unpolarized beam, or a beam with true
               circular polarization, in which no single plane of
               polarization can be determined, the plane should be taken
               as the XZ plane and the angle as 0.

;              (Ip-In)/(Ip+In), where Ip is the intensity
               (amplitude squared) of the electric vector in the plane of
               polarization and In is the intensity (amplitude squared)
               of the electric vector in the plane of the normal to the
               plane of polarization.

               In the case of an unpolarized beam, or a beam with true
               circular polarization, in which no single plane of
               polarization can be determined, the plane is to be taken
               as the XZ plane and the normal is parallel to the Y axis.

               Thus, if there was complete polarization in the plane of
               polarization, the value of
               _diffrn_radiation.polarizn_source_ratio would be 1, and
               for an unpolarized beam
               _diffrn_radiation.polarizn_source_ratio would have a
               value of 0.

               If the X axis has been chosen to lie in the plane of
               polarization, this definition will agree with the definition
               of 'MONOCHROMATOR' in the Denzo glossary, and values of near
               1 should be expected for a bending-magnet source.  However,
               if the X axis were perpendicular to the polarization plane
               (not a common choice), then the Denzo value would be the
               negative of _diffrn_radiation.polarizn_source_ratio.

               See http://www.hkl-xray.com for information on Denzo and
               Otwinowski & Minor (1997).

               This differs both in the choice of ratio and choice of
               orientation from _diffrn_radiation.polarisn_ratio, which,
               unlike _diffrn_radiation.polarizn_source_ratio, is
               unbounded.

;   Example 1 - derived from a suggestion by R. M. Sweet.

   The vector of each axis is not given here, because it is provided in
   the AXIS category.  By making _diffrn_scan_axis.scan_id and
   _diffrn_scan_axis.axis_id keys of the DIFFRN_SCAN_AXIS category,
   an arbitrary number of scanning and fixed axes can be specified for a
   scan.  In this example, three rotation axes and one translation axis
   at nonzero values are specified, with one axis stepping.  There is no
   reason why more axes could not have been specified to step. Range
   information has been specified, but note that it can be calculated from
   the  number of frames and the increment, so the data item
   _diffrn_scan_axis.angle_range could be dropped.

   Both the sweep data and the data for a single frame are specified.

   Note that the information on how the axes are stepped is given twice,
   once in terms of the overall averages in the value of
   _diffrn_scan.integration_time and the values for DIFFRN_SCAN_AXIS,
   and precisely for the given frame in the value for
   _diffrn_scan_frame.integration_time and the values for
   DIFFRN_SCAN_FRAME_AXIS.  If dose-related adjustments are made to
   scan times and nonlinear stepping is done, these values may differ.
   Therefore, in interpreting the data for a particular frame it is
   important to use the frame-specific data.

   There are three date/times in this set: date_set and date_end_estimated, both of which
   are mandatory, because the former is data which can be logged at the start of collection
   and the latter is data than can be estimated at the same time, and date_end which can only
   be logged exactly if the data collection completes normally.

;  Example 2 - a more extensive example (R. M. Sweet, P. J. Ellis &
   H. J. Bernstein).

   A detector is placed 240 mm along the Z axis from the goniometer.
   This leads to a choice:  either the axes of
   the detector are defined at the origin, and then a Z setting of -240
   is entered, or the axes are defined with the necessary Z offset.
   In this case, the setting is used and the offset is left as zero.
   This axis is called DETECTOR_Z.

   The axis for positioning the detector in the Y direction depends
   on the detector Z axis.  This axis is called DETECTOR_Y.

   The axis for positioning the detector in the X direction depends
   on the detector Y axis (and therefore on the detector Z axis).
   This axis is called DETECTOR_X.

   This detector may be rotated around the Y axis.  This rotation axis
   depends on the three translation axes.  It is called DETECTOR_PITCH.

   A coordinate system is defined on the face of the detector in terms of
   2300 0.150 mm pixels in each direction.  The ELEMENT_X axis is used to
   index the first array index of the data array and the ELEMENT_Y
   axis is used to index the second array index.  Because the pixels
   are 0.150mm X 0.150mm, the centre of the first pixel is at (0.075,
   0.075) in this coordinate system.

;   Example 3 - Example 2 revised for a spiral scan (R. M. Sweet,
    P. J. Ellis & H. J. Bernstein).

   A detector is placed 240 mm along the Z axis from the
   goniometer, as in Example 2 above, but in this example the
   image plate is scanned in a spiral pattern from the outside edge in.

   The axis for positioning the detector in the Y direction depends
   on the detector Z axis.  This axis is called DETECTOR_Y.

   The axis for positioning the detector in the X direction depends
   on the detector Y axis (and therefore on the detector Z axis).
   This axis is called DETECTOR_X.

   This detector may be rotated around the Y axis.  This rotation axis
   depends on the three translation axes.  It is called DETECTOR_PITCH.

   A coordinate system is defined on the face of the detector in
   terms of a coupled rotation axis and radial scan axis to form
   a spiral scan.  The rotation axis is called  ELEMENT_ROT  and the
   radial axis is called ELEMENT_RAD.  A 150 micrometre radial pitch
   and a 75 micrometre 'constant velocity' angular pitch are assumed.

   Indexing is carried out first on the rotation axis and the radial axis
   is made to be dependent on it.

   The two axes are coupled to form an axis set ELEMENT_SPIRAL.

              value is given, then only elements of the map for which the

              value of _map_segment.mask_array_id differs from the value of
              _map_segment.array_id in order to permit the mask to be given
              as, say, unsigned 8-bit integers, while the map is given as
              a data type with more range.  However, the two array structures
              must be aligned, using the same axes in the same order with the
              same displacements and increments

;             Data items in the VARIANT category record
              the details about sets of variants of data items.
             
              There is sometimes a need to allow for multiple versions of the
              same data items in order to allow for refinements and corrections
              to earlier assumptions, observations and calculations.  In order
              to allow data sets to contain more than one variant of the same
              information, an optional ...variant data item as a pointer to
              _variant.variant has been added to the key of every category,
              as an implicit data item with a null (empty) default value.
             
              All rows in a category with the same variant value are considered
              to be related to one another and to all rows in other categories
              with the same variant value.  For a given variant, all such rows
              are also considered to be related to all rows with a null variant
              value, except that a row with a null variant value is for which
              all other components of its key are identical to those entries
              in another row with a non-null variant value is not related the
              the rows with that non-null variant value.  This behavior is
              similar to the convention for identifying alternate conformers
              in an atom list.
             
              An optional role may be specified for a variant as the value of
              _variant.role.  Possible roles are null, "preferred",
              "raw data", "unsuccessful trial".
             
              variants may carry an optional timestamp as the value of
              _variant.timestamp.
             
              variants may be related to other variants from which they were
              derived by the value of _variant.variant_of
             
              Further details about the variant may be specified as the value
              of _variant.details.
             
              In order to allow variant information from multiple datasets to
              be combined, _variant.diffrn_id and/or _variant.entry_id may
              be used.

;   Example 1 - Distinguishing between a raw beam center and a refined beam
       center inferred after indexing.  Detector d1 is composed of
       four CCD detector elements, each 200 mm by 200 mm, arranged
       in a square, in the pattern

       detector elements, just beyond the lower right corner of 1,
       the lower left corner of 2, the upper right corner of 3 and
       the upper left corner of 4.  For each element, the detector
       face coordiate system, is assumed to have the fast axis
       running from left to right and the slow axis running from
       top to bottom with the origin at the top left corner.
      
       After indexing and refinement, the center is shifted by .2 mm
       left and .1 mm down.

   0.1   1997-01-24
;
   First draft of this dictionary in DDL 2.1 compliant format by John
   Westbrook (JW).  This version is adapted from the Crystallographic
   Binary File (CBF) Format Draft Proposal provided by Andy Hammersley
   (AH).

   Modifications to the CBF draft.  (JW)

   + In this version the array description has been cast in the categories
     ARRAY_STRUCTURE and ARRAY_STRUCTURE_LIST.  These categories
     have been generalized to describe array data  of arbitrary dimension.

   + Array data in this description are contained in the category
     ARRAY_DATA.  This departs from the CBF notion of data existing
     in some special comment. In this description, data are handled as an
     ordinary data item encapsulated in a character data type.   Although
     data this manner deviates from CIF conventions, it does not violate
     any DDL 2.1 rules.  DDL 2.1 regular expressions can be used to define
     the binary representation which will permit some level of data
     validation.  In this version, the placeholder type code "any" has
     been used. This translates to a regular expression which will match
     any pattern.

     It should be noted that DDL 2.1 already supports array data objects
     although these have not been used in the current mmCIF dictionary.
     It may be possible to use the DDL 2.1 ITEM_STRUCTURE and
     ITEM_STRUCTURE_LIST categories to provide the information that is
     carried in by the ARRAY_STRUCTURE and ARRAY_STRUCTURE_LIST.  By
     moving the array structure to the DDL level it would be possible to
     define an array type as well as a regular expression defining the
     data format.

   + Multiple array sections can be properly handled within a single
     datablock.
