<div class="textblock"><p>Coordinate transformation parameters. </p>
<p>The <b>wcsprm</b> struct contains information required to transform world coordinates. It consists of certain members that must be set by the user (<em>given</em>) and others that are set by the WCSLIB routines (<em>returned</em>). While the addresses of the arrays themselves may be set by <a class="el" href="wcs_8h.html#aab11243b60b10065fc85347bb3efa912" title="Default constructor for the wcsprm struct.">wcsinit()</a> if it (optionally) allocates memory, their contents must be set by the user.</p>
<p>Some parameters that are given are not actually required for transforming coordinates. These are described as "auxiliary"; the struct simply provides a place to store them, though they may be used by <a class="el" href="wcshdr_8h.html#ace387e4a5f6c519ad2a0e1fdebe62381" title="Write out a wcsprm struct as a FITS header.">wcshdo()</a> in constructing a FITS header from a <b>wcsprm</b> struct. Some of the returned values are supplied for informational purposes and others are for internal use only as indicated.</p>
<p>In practice, it is expected that a WCS parser would scan the FITS header to determine the number of coordinate axes. It would then use <a class="el" href="wcs_8h.html#aab11243b60b10065fc85347bb3efa912" title="Default constructor for the wcsprm struct.">wcsinit()</a> to allocate memory for arrays in the <b>wcsprm</b> struct and set default values. Then as it reread the header and identified each WCS keyrecord it would load the value into the relevant <b>wcsprm</b> array element. This is essentially what <a class="el" href="wcshdr_8h.html#ac75623ee805ab7d43b0bba684c719a60" title="FITS WCS parser routine for image headers.">wcspih()</a> does - refer to the prologue of <a class="el" href="wcshdr_8h.html">wcshdr.h</a>.
