PROS

PROS (Post-Reduction Off-line Software) is a package for analysing X-ray astronomy data. It is not specific to any one X-ray astronomy satellite and, in particular, it has facilities to handle data from the EINSTEIN, ROSAT, ASCA and AXAF satellites. It can also be used for non-X-ray data and is particularly suitable for generating pixel masks. It was developed at the Smithsonian Astrophysical Observatory, Cambridge, Massachusetts.
