Documentation on FITS Formats for High Energy Astrophysics

Between 1993-1995, the HEASARC FITS Working Group developed a number of recommendations for FITS format files that stored data relevant to high-energy astrophysics. Although that group has now disbanded, new formats for high-energy astrophysics continue to be developed. The formats documented here are in use by high-energy astrophysics groups and/or software developers.

File Format Description
Chandra FITS files Recommendations for Chandra data product FITS headers
SIMPUT A standard format for source input files to be used in simulations of astronomical observations. This is version 1.1.0 of the format, with slight modifications from the initial version which is available here. More information, including example files, is available here.)
