SAOImage DS9

SAOImage DS9

SAOImage DS9 is an open source 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 via XPA and SAMP.

DS9 is the next version of the popular SAOtng display program. It is a Tk/Tcl application which utilizes the SAOtk widget set. It also incorporates the new X Public Access (XPA) mechanism to allow external processes to access and control its data, GUI functions, and algorithms. DS9 supports the direct display of FITS images and binary tables, multiple frame buffers, region cursor manipulation, many scale algorithms and colormaps, and easy communication with external analysis tasks. It is highly configurable and extensible to meet the evolving needs of the astronomical community. SAOImage DS9 is composed of approximately 20 open source packages.

DS9 is a Tcl/Tk application. The GUI is implemented as a very thin layer of Tk. The first release of SAOImage DS9 was made available in 1999.
