Rarc2pros converts the FITS files for a ROSAT observation into a set of IRAF/PROS files that includes qpoe, image, and tab files. The FITS files must be on disk and the task works on the full set or a subset of the files from the archive in either rationalized data format (RDF) or Rev0 format (US or GERMAN).
