ROSAT All Sky Survey (RASS)
The ROSAT telescope performed an all-sky survey in the X-ray band.
The angular resolution of the ROSAT telescope in
combination with the PSPC camera is approximately 1.8
'.
Original data (WCS format) is be available here: http://www.xray.mpe.mpg.de/cgi-bin/rosat/rosat-survey
