ROSAT Results Archive (SAO)


The ROSAT  Results Archive (RRA) has been produced by the five participating ROSAT  institutions: Max-Planck-Institut für Extraterrestrische Physik (MPE), Goddard Space Flight Center (GSFC), Smithsonian Astrophysical Observatory (SAO), Leicester University (LU), Astrophysikalisches Institut Potsdam (AIP).

It is a public archive that consist of all primary source parameters in all the released ROSAT  High Resolution Imager (HRI) and Position Sensitive Proportional Counter (PSPC) pointed observations: The primary source parameters from the Standard Analysis Software System (SASS) have been quality checked, both by automatic algorithms and by visual inspection of each field. The results of this quality checking are contained as a set of logical-value flags for each principal source parameter. If a source parameter is suspect, the associated flag is set to "TRUE"; parameters with no obvious problems maintain the default, "FALSE", value. The RRA  is based on, and is part of, the ROSAT  Data Archive (RDA). Whereas the current ROSAT  archives contain most of the results from SASS processing of the pointed observations, the RRA  adds the detected source parameters which were previously available only to the Principal Investigator (PI) and the newly generated quality flags.

A HRI RRA Page and PSPC RRA Page have further details and the most recent information.
