NAME

       fit-wcs - Fit a transformation from x,y and matching RA,DEC coordinates

SYNOPSIS

       fit-wcs [options] -x file -r file
       fit-wcs [options] -c file

DESCRIPTION

       Given  a list of x,y coordinates and matching RA,Dec coordinates, fit a transformation and
       produce a WCS file

OPTIONS

       -x file
              XYls input file

       -X name
              X column name (default: FIELD_X)

       -Y name
              Y column name (default: FIELD_Y)

       -r file
              RDls input file

       -R name
              RA column name (default: INDEX_RA)

       -D name
              Dec column name (default: INDEX_DEC)

       -c file
              Correspondences file

       -o file
              WCS output file

       -s sip SIP order (default is a WCS TAN solution, not SIP)

       -W width
              Image width (default: max X position; used for SIP)

       -H height
              Image height (default: max Y position; used for SIP)

       -C     Set CRPIX to be the center of the field; SIP only

       -v     Verbose
