The catalogue can be used for scientific purposes as long as the above publication is referenced.
For each source the ROSAT name, the position in equatorial co-ordinates, the positional error, the source countrate and error, the background countrate, exposure time, hardness-ratios HR1 and HR2 and errors, extent and likelihood of extent, and likelihood of detection are provided. For 94% of the sources visual inspection confirmed the results of the standard processing with respect to existence and position. The remaining 6% have been analyzed using interactive methods; these sources have been flagged. Broad band images are available for a subset of the flagged sources.
A list containing correlations with other catalogues and identifications will follow soon.
