New Features of SAOImage DS9

Joye, William

SAOImage DS9 is an astronomical imaging and data visualization application. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. It provides for easy communication with external analysis tasks and is highly configurable and extensible.

A number of new important features have been developed for DS9. They include:

SAMP: DS9 now supports SAMP. Two methods are available, ds9.get and ds9.set. These methods implement full XPA functionality.

Backup and Restore- When a backup is invoked, DS9 will save in a backup set, all files needed to restore DS9 to that state, including data files, colormaps, catalogs, contours, and regions.

SkyBot- Support for the SkyBot catalog server has been added to DS9.

Colorbar- A number of new colorbar options are now available including size, font, horizontal or vertical layout and numerics distribution.

WCS Editor- A basic WCS editor is now available for adding or modifying WCS keywords.

Datacube- DS9 now supports FITS images up to 10 dimensions.
