Whats New: SAOImageDS9 Version 8.1

New Features

  1. New support for overlaying masks based on world, physical or image coordinates. Each mask is rotated, scaled, and centered upon the specified coordinate system. There is no limit to the number of masks which can be displayed.

  2. An all new plot tool is now available. Each plot tool dialog can contain one or more graphs, arranged in row, column, or grid order. In addition, a new strip plot layout is also available. Support for line, bar, or scatter graphs are provided. Each graph has its own set of display parameters and can contain one or more data sets. Each plot dialog maybe printed as a postscript image, or exported as tiff, png, jpeg, or gif.

  3. The movie feature now supports animated GIFs. 3D data cubes, or a sequence of multiple frames can be animated, and saved as an animated GIF to be displayed on the desktop, in twitter or on a web site.

  4. The MacOS Aqua port now supports 'Dark Mode' for MacOS Mojave and Catalina users. The appearance of all dialogs, menus, and displays will be rendered based on the current MacOS appearance settings.

  5. Contours have been reimplemented to provide high quality resolution and have been threaded to take advantage of multiple CPUs, providing fast rendering, especially in the case of 3D data cubes.

JS9: Image Display Right in Your Browser

SAOImage JS9 is a JavaScript version of the de facto standard DS9 image display program. It allows you to view and manipulate astronomical image data in your browser:

  1. display FITS images and binary tables

  2. change the colormap and scale

  3. manipulate the contrast/bias with the mouse

  4. display pixel values and WCS position information

  5. manipulate geometric regions of interest

  6. perform data analysis

Please visit the JS9 page for more information.

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) with additional funding from the JWST Mission office at Space Telescope Science Institute.
