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.
