NAME

       wcsware - Extract WCS keywords for an image

SYNOPSIS

       wcsware [-a<alt>] [-f] [-h<hdu>] [-p] [-x] [<fitsfile>]

DESCRIPTION

       wcsware  extracts  the  WCS keywords for an image from the specified FITS file, constructs
       wcsprm structs for  each  coordinate  representation  found  and  performs  a  variety  of
       operations using them.

       The  FITS file may be specified according to the syntax understood by cfitsio, for example
       "file.fits.gz+1" refers to the first extension of a gzip'd FITS file.  Use "-" or omit the
       file name for input from stdin.

OPTIONS

       -a<alt>
              Specify an alternate coordinate representation to be used (ignored if there is only
              one).

       -f     Apply wcsfix() to the header.

       -h<hdu>
              Move to HDU number (1-relative) which  is  expected  to  contain  an  image  array.
              (Useful for input from stdin.)

       -p     Print the struct(s) using wcsprt() (default operation).

       -P     Same as -p but don't print a default struct.

       -x     Convert  pixel  coordinates,  obtained  from  stdin,  to  world  coordinates  using
              wcsp2s().

       -w     Convert  world  coordinates,  obtained  from  stdin,  to  pixel  coordinates  using
              wcss2p().
