Description
The Hamburg/ROSAT All-Sky Survey (RASS) Catalog lists 5,341 X-ray sources from the ROSAT Bright Source Catalog, covering approximately 10,000 square degrees of the sky at galactic latitudes |b| >= 30 degrees and declination Dec >= 0 degrees. NASA HEASARC produced this table in February 2005 based on source data from the Centre de Données astronomiques de Strasbourg (CDS). For 82% of the selected sources, an optical identification was provided, with AGN representing the largest group at ~42%.
Use Cases
Selecting complete samples of X-ray emitters based on the catalog's classification of sources into AGN, stars, galaxies, and clusters.
Cross-matching X-ray source positions with optical survey data based on the described use of digitized Hamburg Quasar Survey plates.
Analyzing the distribution and properties of high-galactic latitude X-ray sources based on the catalog's coverage of ~10,000 square degrees.
Studying the identification success rate for X-ray sources based on the stated 82% identification rate and the ~3% with no visible optical counterpart.
Strengths
Covers 5,341 X-ray sources from a well-defined survey (ROSAT Bright Source Catalog).
Provides optical identifications for 82% of the selected sources.
