Rosat Bright Survey
(list of bright X-ray sources from ROSAT observations)
The Rosat Bright Survey (designated as RBS) is a list of
bright X-ray sources collected from ROSAT observations
during the 1990s. It is a list/sample of X-ray sources
from regions of the sky explored by ROSAT, selected by an
X-ray brightness cutoff.
It includes identification, associating the sources to objects
in other non-X-ray surveys and observations.
Among its objects are X-ray active galactic nuclei.
