The ROSAT all-sky survey

The ROSAT (Röntgensatellit) X-ray astronomy satellite has completed the first all-sky X-ray and XUV survey with imaging telescopes. About 60,000 new X-ray and 400 new XUV /1/ sources were detected. This contribution will deal with preliminary results from the ROSAT ALL-SKY X-RAY SURVEY. The ROSAT diffuse and point-source X-ray skymaps, the positional accuracy obtained for the X-ray sources, and a few results from correlations performed with available catalogues in various energy bands like the Radio, Infrared, Visible, UV, and hard X-rays as well as identifications from optical follow-up observations are presented.
