Second ROSAT All-Sky Survey Point Source Catalog (2RXS)
This database table contains the Second ROSAT All-Sky Survey Point Source Catalog (2RXS). This is the second publicly released ROSAT catalog of point-like sources obtained from the ROSAT All-Sky Survey (RASS) observations performed with the Position-Sensitive Proportional Counter (PSPC) between June 1990 and August 1991. It is an extended, revised, and combined version of the RASS <a href="/W3Browse/rosat/rassbsc.html">Bright</a> and <a href="/W3Browse/rosat/rassfsc.html">Faint Source Catalog</a>s. Utilizing the latest RASS processing, this catalog includes more than 135,000 X-ray detections in the 0.1-2.4 keV energy band down to a likelihood threshold of 6.5. Additional information can be found at <a href="http://www.mpe.mpg.de/ROSAT/2RXS/">http://www.mpe.mpg.de/ROSAT/2RXS/</a>. This table was created by the HEASARC in March, 2017, based on <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/588/A103">CDS Catalog J/A+A/588/A103</a> file cat2rxs.dat.gz.
