THE FIRST ROSAT SOURCE CATALOG

During the ROSAT workshop at MPE on October 26, 1994 Wolfgang Voges announced on behalf of the ROSAT Consortium (MPE-Garching, GSFC/SAO-US, and WFC-Consortium-UK) the public release of "THE FIRST ROSAT SOURCE CATALOGUE OF POINTED OBSERVATIONS WITH THE PSPC". This catalogue contains 50,408 sources from 2876 pointed observations. For each source the following properties are provided: the observation number, the ROSAT name, the position in equatorial and in galactic co-ordinates, four positional errors (intrinsic, systematic, boresight, and total), the source count-rate and its error, the background countrate, exposure time, hardness-ratios HR1 and HR2 and their errors, extent and likelihood of extent, likelihoods of the map-detect algorithm and of the maximum-likelihood detection algorithm, flags to indicate in which energy band and by what algorithm the source was detected, the detection cell size, the off-axis radius, the distances to the nearest rib and source (before and after removal of ambiguous sources), and a source confusion flag (set if another source is within 2.1*FWHM of the point-spread function).

Abstract

We have taken all the data contained in the ROSAT public archive and generated a catalog of 45,000 point sources. This catalog has been made public through the "http://heasarc.gsfc.nasa.gov/0" HEASARC and "http://www.esrin.esa.it/htdocs/esis/esis.html" ESIS online services. The detection technique uses a sliding box and has been optimized for point source detection. A K-S test for variability has been made and a number of variable sources identified. A hardness and softness ratio is also used to identify unusually soft or hard sources. Cross-correlations against the major optical, radio, x-ray and ir catalogs are presented.
