Producing the ROSAT bright source catalogue: the screening process.
Abstract
The ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision IRXS) derived from the all-sky survey performed during the first half year of the ROSAT mission in 1990/91 has been produced based on a revised processing by the standard analysis software system (SASS). Despite the fact that SASS already improved source detection considerably, a visual screening proved to be essential to guarantee reliable input to the catalogue. The screening process and the source flags representing the result of screening are described and visualized by examples. For a special subset of sources offline postprocessing of the source parameters was found to be useful.
