SAOImage DS9: Astronomical Data Visualization Application

    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 Sun Solaris, Linux, Linux64, MacOSX, and Windows XP.
 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. DS9 also supports FTP and HTTP

    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.

    DS9 is a Tk/Tcl application which utilizes the SAOTk widget set. It also
incorporates the X Public Access (XPA) mechanism to allow external processes to access
and control its data, GUI functions, and algorithms.

    New releases of the DS9 binaries, including new features and bug fixes, are made
available four times a year in January, April, July, and October.

The XPA Messaging System

The XPA messaging system provides seamless communication between many kinds of Unix
programs, including X programs and Tcl/Tk programs. It also provides an easy way for
users to communicate with these XPA-enabled programs by executing XPA client commands
in the shell or by utilizing such commands in scripts. Because XPA works both at
the programming level and the shell level, it is a powerful tool for unifying any
analysis environment: users and programmers have great flexibility in choosing the best
level or levels at which to access XPA services, and client access can be extended or
modified easily at any time.

A program becomes an XPA-enabled server by defining named points of public access
through which data and commands can be exchanged with other client programs (and users).
Using standard TCP sockets as a transport mechanism, XPA supports both single-point and
broadcast messaging to and from these servers. It supports direct communication between
XPA clients and servers, or indirect communication via an intermediate message bus
emulation program. Host-based access control is implemented, as is as the ability
to communicate with XPA servers across a network.

Because XPA consists of a library and a set of user programs, it is most appropriately
built from source. XPA has been ported to Solaris, Linux, Mac OSX (darwin) and
Windows 98/NT/2000/XP. Once the source code tar file is retrieved, XPA can be built and
installed easily using standard commands:

  ./configure --prefix=[installdir] 	# configuration
  make					# build the software
  make install				# install in [installdir]
