Samples of FITS files which use WCS conventions Don Wells September 23, 1994 The files in this directory use FITS syntactic and semantic conventions which are upwardly compatible with those described in the draft document ftp://fits.cv.nrao.edu/fits/documents/wcs/wcs.all.ps.Z. The *.lst files are listings of the FITS headers. The pairs of radio and optical imagery have been re-gridded so that they are suitable for 'blink' comparison. One pair uses the 'ARC' projection, the other uses 'SIN'. Both IRAF and AIPS can interpret the coordinate information in these headers. I will be delighted to receive additional examples of WCS usage.
