![]() 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. SAOImage DS9 - Astronomical Imaging and Data Visualization Application: DS9 supports. The new project was referred to, jokingly, as DS9 (Deep Space 9), the logical extension of the Star Trek series. Define your own collaboration groups, share code and results, etc. It provides for easy communication with external analysis tasks and is highly configurable and extensible via XPA and SAMP. It supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. This project was funded by the NASA Applied Information Systems Research Program, under the title "Future Directions for Astronomical Image Display". SAOImageDS9 is an astronomical imaging and data visualization application. 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. The only difference is that DS9 is double buffered, whereas, saoimage and ximtool only use a single buffer.In fact, DS9 uses the same code to interface with IRAF as saoimage and ximtool. It explored new GUI interfaces and supported a new external analysis interface.DS9 and saoimage are similar in speed when working with IRAF.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. coordinates as most astronomy applications do: ds9, SAOImage, SExtractor. It supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms. Since Mike's departure from SAO, SAOImage has been maintained by Jessica Mink. A class for storing image data along with the pixel scale or WCS information. SAOImage DS9 is an astronomical imaging and data visualization application. SAOImage was a brilliant program, implementing techniques in scientific visualization 30 years ago that are still being used by today's applications. If the WCS info is defined for each system (or if they have the same image pixel scale), use Frame > Match Frames to align them for comparison. In fact, it was one of the first X11 based applications publicly made available. SAOImage was first implemented in X10, then reimplemented in X11. Additional funding was provided by the JWST Mission office at Space Telescope Science Institute to improve capabilities for 3-D data visualization.In 1990, Mike Van Hilst, at the Smithsonian Astrophysical Observatory, Center for Astrophysics, Harvard University, developed SAOImage under the direction of Eric Mandel. SAOImageDS9 development has been made possible by funding from the Chandra X-ray Science Center (CXC) and the High Energy Astrophysics Science Archive Center (HEASARC). GUI elements such as the coordinate display, panner, magnifier, horizontal and vertical graphs, button bar, and color bar can be configured via menus or the command line. All versions and platforms support a consistent set of GUI and functional capabilities.ĭS9 supports advanced features such as 2-D, 3-D and RGB frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, cropping, rotation, pan, and a variety of coordinate systems. ![]() It requires no installation or support files.
