NAME

       ds9 - image tool for astronomy

SYNOPSIS

       ds9 [options]

DESCRIPTION

       DS9  DS9  is  the  modern image tool used by astronomers for visualization of astronomical
       data.  It supports a plethora of command line options, which may be used in a  script-like
       fashion.   An  instance  of the program is entirely controllable from the commandline with
       the XPA tools.
