image display tool for astronomy

DS9 is an application for astronomical imaging and data visualization.

DS9 is the modern imtool used by astronomers. It is most distinguished by its support for displaying images of high dynamic range (such as 16 bit greyscale FITS files). Whereas many other tools will only read an approximation to such files, DS9 works in full precision, and uses various display parameters to map input data into 8 bit data which can be displayed on the screen.

Available parameters for the mapping include: brightness, contrast, false color, and nonlinear input mapping (such as logarithm, square root, square, etc.)

Although it may be useful in other fields, DS9 includes a fair number of features specific to astronomy. There is an astronomical "name resolver" which allows a lookup of an arbitrary named object to its coordinates. Given the coordinates of a field, online archive servers may be queried, and an image retrieved. DS9 thusly implements a preliminary "Virtual Observatory".

DS9 is entirely controllable from external programs ("XPA"), which simplifies complex tasks such as data acquisition, realtime display, and batch analysis.

If images include WCS (World Coordinate System) keywords, then they may be "blinked" to search for moving or changing objects. .
