Abstract

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.  Provenance:  Max Planck Institute for Exterrestrial Physics (Garching FRG). This is a service of NASA HEASARC.
