Description


The ROSAT All-Sky X-ray Survey was obtained during 1990/1991 using the ROSAT Position Sensitive Proportional Counter (PSPC) in combination with the ROSAT X-ray Telescope (XRT). More than 60,000 X-ray sources were detected during this time. <p> SkyView has multiple surveys derived from the RASS data. The surveys whose RASS are counts and exposure maps from the survey. Previously The RASSBCK maps have had the point sources removed to show the diffuse X-ray background and are presended at lower resolution. <p> The full-resolution RASS surveys data are organized in 1378 fields each 6.4&amp;#176;; x 6.4&amp;#176;; covering the whole sky. Neighboring fields overlap by at least 0.23&amp;#176;;.<p> Three bands are available through <i>SkyView</i> <UL> <LI> broad band (0.1-2.4 keV) <LI> hard band (0.5-2.0 keV) <LI> soft band (0.1-0.4 keV) </ul> Data was dowloaded from the <a href="https://www.xray.mpe.mpg.de/rosat/survey/rass-3/main/help.html#ftp">MPE FTP site</a>. <p> The intensity maps are created from the exposure maps using the single exposure map available which is appropriate for the broad band images, so the intensities of the hard and soft bands are only approximate.
