FTOOLS: The OSO8 Sub-package

The OSO8 sub-package of FTOOLS contains mission-specific tasks for the OSO8 mission. These tools extract lightcurves for the B and C detectors on the OSO8 Goddard Cosmic X-ray Spectrometer Experiment. They work on the OSO8 rate data files in fits format as available in the HEASARC archive.

The following OSO8 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}.
