DS9 Description
---------

SAOImage DS9 is an astronomical imaging and data visualization
application. DS9 supports FITS images and binary tables, multiple
frame buffers, region manipulation, and many scale algorithms and
colormaps. It provides for easy communication with external analysis
tasks and is highly configurable and extensible.

DS9 is a stand-alone application. It requires no installation or
support files. Versions of DS9 currently exist for Solaris, Linux,
Windows, and MacOSX . All versions and platforms support a consistent
set of GUI and functional capabilities.

DS9 supports advanced features such as multiple frame buffers, mosaic
images, tiling, blinking, geometric markers, colormap manipulation,
scaling, arbitrary zoom, rotation, pan, and a variety of coordinate
systems.

The GUI for DS9 is user configurable. GUI elements such as the
coordinate display, panner, magnifier, horizontal and vertical graphs,
button bar, and colorbar can be configured via menus or the command
line.
