  • The Third ROSAT High Resolution Imager Source Catalog:

    The ROSAT Consortium (the Max-Planck-Institut fuer extraterrestrische Physik, the Goddard Space Flight Center, the Smithsonian Astrophysical Observatory, Leicester University, and the Astrophysikalisches Institut Potsdam) announces the release of the completed source catalogs of all ROSAT pointed observations.

    "THE FIRST ROSAT SOURCE CATALOG OF POINTED OBSERVATIONS WITH THE HIGH RESOLUTION IMAGER (ROSHRICAT / 1RXH)" contains arcsecond positions and count rates of 56,401 detected sources from 5393 ROSAT HRI observations covering 1.94% of the sky, including 13,452 high confidence detections and 331 obvious sources which were not detected by the SASS.

    The catalogs consist of all primary source parameters from the automated detection algorithm employed by the SASS. In addition each observation has been quality checked, both by automatic algorithms and by detailed visual inspection. 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.

    Detailed information about the catalog and methods of access to the catalog and data products can be obtained from the ROSAT Results Archive web pages in Germany, in the US, and in the UK:

    The ROSAT Source Catalogs will be modified if necessary. New versions will be announced on the RRA web sites at MPE, GSFC, SAO, AIP and Leicester.
