SAOImage DS9 Version 5.0 New Features

MacOSX Aqua Support

DS9 has been ported to MacOSX Aqua and is an universal application which no longer requires X11.

Compressed FITS Support

DS9 supports compressed FITS images using RICE, HCOMPRESS, and GZIP compression.

Mask Support

DS9 supports overlay masks. A mask is defined as a valid FITS image, in which a non zero value indicates that the selected mask color is to be displayed instead of the data value color.

SkyView Support

DS9 provides support for HEASARC's image cutout service, SkyView. This site provides image cutout service for a number of image surveys, including SDSS.

Multi-Language Support

DS9 provides multi-language support. By default, the language used for menus and dialog boxes is based on the value of the operating system locale variable. The user may override the default value by selecting the desired language in the preferences or by the -language command line option.

Preferences

Preferences are automatically saved when a user changes an option. Selecting the saving preferences menu item is no longer needed.
