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).

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

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