<h1><a class="anchor" name="software">FITS-WCS and related software </a></h1>Several implementations of the FITS WCS standards are available:<p>
<ul>
<li>The <a class="el" href="overview.html">WCSLIB</a> software distribution (i.e. this library) may be obtained from <a href="http://www.atnf.csiro.au/~mcalabre/WCS/">http://www.atnf.csiro.au/~mcalabre/WCS/</a><em></em>. The remainder of this manual describes its use.</li></ul>
<p>
<ul>
<li><b>wcstools</b>, developed by Doug Mink, may be obtained from <a href="http://tdc-www.harvard.edu/software/wcstools/">http://tdc-www.harvard.edu/software/wcstools/</a><em></em>.</li></ul>
<p>
<ul>
<li><b>AST</b>, developed by David Berry within the U.K. Starlink project, <a href="http://www.starlink.ac.uk/ast/">http://www.starlink.ac.uk/ast/</a> and now supported by JAC, Hawaii <a href="http://starlink.jach.hawaii.edu/starlink/">http://starlink.jach.hawaii.edu/starlink/</a><em></em>. <br>
<br>
A useful utility for experimenting with FITS WCS descriptions (similar to <em>wcsgrid</em>) is also provided; go to the above site and then look at the section entitled "FITS-WCS Plotting Demo".</li></ul>
<p>
<ul>
<li><b>SolarSoft</b>, <a href="http://sohowww.nascom.nasa.gov/solarsoft/">http://sohowww.nascom.nasa.gov/solarsoft/</a><em></em>, primarily an IDL-based system for analysis of Solar physics data, contains a module written by Bill Thompson oriented towards Solar coordinate systems, including spectral, <a href="http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/wcs/">http://sohowww.nascom.nasa.gov/solarsoft/gen/idl/wcs/</a><em></em>.</li></ul>
<p>
<ul>
<li>The IDL Astronomy Library, <a href="http://idlastro.gsfc.nasa.gov/">http://idlastro.gsfc.nasa.gov/</a><em></em>, contains an independent implementation of FITS-WCS in IDL by Rick Balsano, Wayne Landsman and others. See <a href="http://idlastro.gsfc.nasa.gov/contents.html#C5">http://idlastro.gsfc.nasa.gov/contents.html#C5</a><em></em>.</li></ul>
<p>
Python wrappers to <a class="el" href="overview.html">WCSLIB</a> are provided by<p>
<ul>
<li>The <b>Kapteyn Package</b> <a href="http://www.astro.rug.nl/software/kapteyn/">http://www.astro.rug.nl/software/kapteyn/</a> by Hans Terlouw and Martin Vogelaar.</li></ul>
<p>
<ul>
<li><b>pywcs</b>, <a href="http://stsdas.stsci.edu/astrolib/pywcs/">http://stsdas.stsci.edu/astrolib/pywcs/</a> by Michael Droettboom.</li></ul>
<p>
Java is supported via<p>
<ul>
<li>CADC/CCDA Java Native Interface (JNI) bindings to <a class="el" href="overview.html">WCSLIB</a> 4.2 <a href="http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/cadc/source/">http://www.cadc-ccda.hia-iha.nrc-cnrc.gc.ca/cadc/source/</a> by Patrick Dowler.</li></ul>
<p>
Recommended WCS-aware FITS image viewers:<p>
<ul>
<li>Bill Joye's <b>DS9</b>, <a href="http://hea-www.harvard.edu/RD/ds9/">http://hea-www.harvard.edu/RD/ds9/</a><em></em>, and</li></ul>
<p>
<ul>
<li><b>Fv</b> by Pan Chai, <a href="http://heasarc.gsfc.nasa.gov/ftools/fv/">http://heasarc.gsfc.nasa.gov/ftools/fv/</a><em></em>.</li></ul>
<p>
both handle 2-D images.<p>
Currently (2011/08/05) I know of no image viewers that handle 1-D spectra properly nor multi-dimensional data, not even multi-dimensional data with only two non-degenerate image axes (please inform me if you know otherwise).<p>
Pre-built <a class="el" href="overview.html">WCSLIB</a> packages are available, generally a little behind the main release (this list will probably be out-of-date by the time you read it, best do a web search):<p>
<ul>
<li>Fedora (RPM), <a href="https://admin.fedoraproject.org/pkgdb/packages/name/wcslib">https://admin.fedoraproject.org/pkgdb/packages/name/wcslib</a><em></em>.</li></ul>
<p>
<ul>
<li>Fresh Ports (RPM), <a href="http://www.freshports.org/astro/wcslib/">http://www.freshports.org/astro/wcslib/</a><em></em>.</li></ul>
<p>
<ul>
<li>Gentoo, <a href="http://packages.gentoo.org/package/sci-astronomy/wcslib">http://packages.gentoo.org/package/sci-astronomy/wcslib</a><em></em>.</li></ul>

<p>
Bill Pence's general FITS IO library, <b>CFITSIO</b> is available from <a href="http://heasarc.gsfc.nasa.gov/fitsio/">http://heasarc.gsfc.nasa.gov/fitsio/</a><em></em>. It is used optionally by some of the high-level WCSLIB test programs and is required by two of the utility programs.<p>
<b>PGPLOT</b>, Tim Pearson's Fortran plotting package on which <a class="el" href="pgsbox.html">PGSBOX</a> is based, also used by some of the WCSLIB self-test suite and a utility program, is available from <a href="http://astro.caltech.edu/~tjp/pgplot/">http://astro.caltech.edu/~tjp/pgplot/</a><em></em>. </div>
