FTOOLS: The HEASARC Sub-package


The HEASARC sub-package of FTOOLS contains tasks for High Energy (X- & gamma-ray) astronomy that are not specific to a particular instrument.

The following HEASARC tasks were released in the latest distribution of the HEASARC's FTOOLS package. Each task is hyperlinked to the help file distributed with the task. The same information can be obtained while running FTOOLS by typing the command fhelp {taskname}.

If you require further, or more detailed information on the HEASARC sub-package of tasks, contact

ftoolshelp@athena.gsfc.nasa.gov
