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.
