![]() ![]() In fact, DS9 uses the same code to interface with IRAF as saoimage and ximtool. Since we will be binning on the coordinates (RA, DEC), this means we will have.DS9 and saoimage are similar in speed when working with IRAF.# Check back to see what the current color scale is. ds9 (image viewer) download and install from Harvards: SAOImage DS9. # Now you can play in ds9 to your heart's content. set ( 'zoom to fit' ) # Change the colormap and scalingĭ. pdf (yy ) # Now open ds9 (this assumes no ds9 instance is yet running)ĭ = ds9. Since then, the popularity of DS9 has grown far beyond expectations.# Make a 2D gaussian image that is stored in a 2D numpy array The first versions of DS9 were made available in 1999. The distributed binaries consist of a self-contained self-extracting archive and application, which provides an independent Tcl/Tk environment without installation. The current version of DS9 is composed of the Tk widgets created along with support from about 20 other open source products (including Tcl/Tk, AST, BLT, HCompress, HTMLWidget, plio, rics, tcllib, tclxml, tkcon, tkimg, tktable, wcssubs, xmlrpc, XPA, zip, zlib, and zvfs). It provides for easy communication with external analysis tasks and is highly configurable and extensible via XPA and SAMP. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. However, all the visualization techniques come directly from SAOImage. SAOImage DS9 is an astronomical imaging and data visualization application. DS9 inherited TNG's support of regions, XPA, external analysis support, and the general GUI. Basically, all the real work is done in C++. A number of Tk Canvas widgets in C++ were created to support all the functionality needed. The GUI is implemented as a very thin layer of Tk. Current funding is provided by the NASA High Energy Astrophysics Science Archive Center and the Chandra X-ray Science Center.ĭS9 is a Tcl/Tk application.

For lack of a name, the new project was referred to as DS9, the logical extension of the Star Trek series. SAOImage DS9 is an astronomical imaging and data visualization application. 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. SAOImage DS9 is an astronomical imaging and data visualization application. Since Mike's departure from SAO, SAOImage has been maintained by Jessica Mink. Saoimage DS9 Reference Manual Package 'Fitsio' Astronomy Visualization Metadata Standard Image Cropping, Resizing, and Saving in JPEG Format This Is a DRAFT of an RFC for Obtaining MIME Types for FITS. SAOImage was a brilliant program, implementing techniques in scientific visualization 20 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. In 1990, Mike Van Hilst, at the Smithsonian Astrophysical Observatory, Center for Astrophysics, Harvard University, developed SAOImage.
