section=xanes
section_description
These variables set parameters related to Demeter's special treatment
of XANES data.
variable=nnorm
type=list
options=1 2 3
default=2
description
This is the default value for normalization order for XANES data.
variable=nor1
type=real
default=15
units=eV (relative to e0)
description
This is the default value for the lower bound of the normalization
range. This should be positive, but not so large that it is outside
the range of the data. A negative value means to set nor2 to that
many volts before the final data point.
variable=nor2
type=real
default=0
units=eV (relative to e0)
description
This is the default value for the ipper bound of the normalization
range. This should be positive. If the value is 0 or such that it
is beyond the range of data, then nor2 will be set to the last data
point. A negative value means to set nor2 to that many volts before
the final data point.
variable=cutoff
type=real
default=100
units=eV
description
As Athena begins to import a data file, a check is performed to try
to guess if a mu(E) data file is actually a XANES measurement as
opposed to an EXAFS measurement. This distinction is fairly
arbitrary. If the difference between the initial quass of e0 and
last energy point is smaller than this value, then we presume that
these are XANES data. One impact of this identification is to reset
the normalization range boundaries. Set this value to 0 to skip the
test.
