8.4 Data Output of the All-Sky Survey

The main objectives of the first all-sky survey in soft X-rays have been the creation of a catalogue with X-ray sources and their properties [Voges et al.1995, Voges et al.1996, Voges et al.1997, Voges1997, Gruber et al.1997] and the generation of a sky map of the diffuse X-ray background [Snowden et al.1995a]. SASS correlates the ROSAT all-sky survey sources (RASS) recorded by the PSPC detector with the about entries of the SIMBAD catalogue as well as with 94 user-supplied catalogues with approximately entries. These user-supplied catalogues --classified according to their observation method (radio, IR, X-ray, -ray band) or their object class (stars, galaxies, cluster of galaxies, supernova remnants, cataclysmic variables)-- are supplied by the ROSAT scientific working groups at MPE to help in identifying the new X-ray sources. In addition, for each RASS source finding charts are produced for follow-up observations using the ROE/NRL object catalogue for the southern sky (on-line) and the APM object catalogue for the northern sky (on-line) [Voges1992].
