In general, directories correspond to specific missions, e.g., rosat to ROSAT, asca to ASCA, etc., with the following exceptions: the caldb directory contains some multi-mission calibration data (mission specific caldb data are credited to the mission not to caldb), fits_info contains FITS-related files, heasarc contains complete database catalogs, and software contains multi-mission software.
