       astscript-fits-view - View FITS images in DS9 and tables in TOPCAT

SYNOPSIS

       astscript-fits-view [OPTION] FITS-file(s)

DESCRIPTION

       This script is part of GNU Astronomy Utilities 0.22.

       This  script  will  take any number of FITS inputs and will pass them to TOPCAT or SAO DS9
       depending on the the first input FITS file: if it contains an image HDU, the files will be
       passed to SAO DS9, otherwise, to TOPCAT.

       For  more  information,  please run any of the following commands. In particular the first
       contains a very comprehensive explanation of this script's invocation: expected  input(s),
       output(s), and a full description of all the options.
