DPUSER is an interactive language that is capable of handling numbers (both
real and complex), strings, and matrices. Its main aim is to do astronomical
image analysis, for which it provides a comprehensive set of functions,
but it can also be used for many other applications.
QFitsView is a FITS file viewer. In addition to displaying two-dimensional images, it also provides means to explore three-dimensional data cubes.

DPUSER has been ported to several platforms. For instructions how to get and install DPUSER, go to the installing page.
DPUSER is a text-console program and therefore can be run on any terminal. On startup, you are greeted by a short message and the DPUSER> prompt appears. Now you are ready to type commands. As in a UNIX-shell, you can use the up- and down keys to browse previously typed commands. Filename expansion using the tab-key is also supported. When run in the Windows Environment, a GUI frontend called windpuser can be started which provides similar functionality.
