![]() The name continues to be in use! Current funding is provided by the Chandra X-ray Science Center and the NASA High Energy Astrophysics Science Archive Center. The new project was referred to, jokingly, as DS9 (Deep Space 9), the logical extension of the Star Trek series. This project was funded by the NASA Applied Information Systems Research Program, under the title "Future Directions for Astronomical Image Display". In 1998, while working with Eric, William Joye began a complete rewrite of TNG, based on the experience developed while supporting TNG. In particular, it utilized XPA, (X11 Public Access, also written by Eric) which allowed TNG to be scripted via a shell, or from other application. It explored new GUI interfaces and supported a new external analysis interface. TNG was based on IRAF's XIMTOOL graphics libraries and Tcl. In the mid 1990's, with the administrative support of Steve Murray, Eric Mandel developed SAOtng, or (SAOImage, The Next Generation), named after the Star Trek series. There are several output options, such as JPEG and PS, which are useful when producing images for the web and publication. Since Mike's departure from SAO, SAOImage has been maintained by Jessica Mink. SAOImage ds9, the imaging application distributed with CIAO, has the capability for users to create an RGB image and interactively adjust many of its parameters to achieve optimal results. SAOImage was a brilliant program, implementing techniques in scientific visualization 30 years ago that are still being used by today's applications. In fact, it was one of the first X11 based applications publicly made available. SAOImage was first implemented in X10, then reimplemented in X11. These include tasks such as spectral extraction and. ![]() ![]() Recent changes have greatly improved the capabilities of the dax analysis menu, which lets you run a number of CIAO tasks from the DS9 analysis menu. In 1990, Mike Van Hilst, at the Smithsonian Astrophysical Observatory, Center for Astrophysics, Harvard University, developed SAOImage under the direction of Eric Mandel. CIAO 4.15 comes with version 8.4.1 of SAOImage DS9, which can be used to visualize images, event files, and even tabular data. ![]()
