NB: with the release of our new ds9 image display program, we consider SAOtng to be retired. Please upgrade to ds9 at your earliest convenience.
SAOimage is an X Window System image display program that has been used by thousands of astronomers throughout the world during the past decade. In this age of "open software", it needs updating to support:
We have utilized XPA to develop "SAOimage: The Next Generation" (SAOtng), an extensible image display service that can cooperate with other processes and programs. SAOtng supports advanced features such as:
In addition, through XPA, open software functionality has been added to SAOtng at many levels. All of the SAOtng menu functions are defined to be XPA public access points, allowing SAOtng to be controlled directly through its GUI or externally by other programs. XPA also is used to "externalize" algorithms such as image file access and data scaling, so that new file formats and scales can be added without re-compilation. Finally, XPA is used to support user-configurable "quick-look" analysis of image data and bi-directional communication with other processes.
SAOtng has been ported to Linux, Solaris, SunOS, Dec Alpha OSF1, HP/UX, and SGI. Twelve releases of the program were made as part of the SAORD software suite between 1995 and 2000, when it was replaced by its successor, DS9.
The SAORD 1.9.1 source code tar files for all platforms (saord-1.9.1.tar.[gz,Z]) are available here:
SAORD 1.9.1 binary distribution tar files (saord-1.9.1-[arch].tar.[gz,Z]) are available here:Documentation for SAOtng and other SAORD software can be accessed on-line:
SAOtng was developed with support from NASA's Applied Information Systems Research Program.
