The RASS-BSC is derived from the all-sky survey performed during the first half year of the ROSAT mission in 1990/91. 18,811 sources are catalogued, with a limiting ROSAT PSPC countrate of 0.05 cts/s in the 0.1-2.4 keV energy band. The sources have a detection likelihood of at least 15 and contain at least 15 source photons. At a brightness limit of 0.1 cts/s (8,547 sources) the catalogue represents a sky coverage of 92%. The typical positional accuracy is 30 arcsec. The RASS-FSC is derived from the all-sky survey performed during the ROSAT mission in the energy band 0.1- 2.4 keV. 105,924 sources are catalogued and represent the faint extension to the RASS bright source catalogue. The sources have a detection likelihood of at least 7 and contain at least 6 source photons. (The likelihood of source detection is defined as L =-ln (1-P) , with P = probability of source detection). http://www.mpe.mpg.de/xray/wave/rosat/index.php?lang=en Catalog Research service-for ivo://wfau.roe.ac.uk/rosat-dsa/ceaApplication rosat_bsc table: cone search of Bright Source Catalog http://wfaudata.roe.ac.uk/rosat-dsa/DirectCone?DSACAT=ROSAT&DSATAB=rosat_bsc& 1.500000 2000000 false 96.0 5.0 1.0 rosat_fsc table: cone search of Faint Source Catalog http://wfaudata.roe.ac.uk/rosat-dsa/DirectCone?DSACAT=ROSAT&DSATAB=rosat_fsc& 1.500000 2000000 false 96.0 5.0 1.0 http://wfaudata.roe.ac.uk/rosat-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/rosat-dsa/VOSI/capabilities GET application/xml http://wfaudata.roe.ac.uk/rosat-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/rosat-dsa/VOSI/availability GET application/xml http://wfaudata.roe.ac.uk/rosat-dsa/VOSI/tables GET application/xml http://wfaudata.roe.ac.uk/rosat-dsa/delegations GET application/xml X-ray ROSAT The query response table.
