Abstract:
We present the catalogue of the REFLEX Cluster Survey providing
information on the X-ray properties, redshifts, and some
identification details of the clusters in the REFLEX sample. The
catalogue describes a statistically complete X-ray flux-limited sample
of 447 galaxy clusters above an X-ray flux of 3x10-12erg/s/cm2
(0.1 to 2.4keV) in an area of 4.24ster in the southern sky. The
cluster candidates were first selected by their X-ray emission in the
ROSAT-All Sky Survey and subsequently spectroscopically identified in
the frame of an ESO key programme. Previously described tests have
shown that the sample is more than 90% complete and there is a
conservative upper limit of 9% on the fraction of clusters with a
dominant X-ray contamination from AGN. In addition to the cluster
catalogue we also describe the complete selection criteria as a
function of the sky position and the conversion functions used to
analyse the X-ray data. These are essential for the precise
statistical analysis of the large-scale cluster distribution. This
data set is at present the largest, statistically complete X-ray
galaxy cluster sample. Together with these data set we also provide
for the first time the full three-dimensional selection function. The
sample forms the basis of several cosmological studies, one of the
most important applications being the assessment of the statistics of
the large-scale structure of the universe and the test of cosmological
models. Part of these cosmological results have already been
published.
Description:
The following tables provide the catalogue as well as several data
files necessary to reproduce the sample preparation. These files are
also required for the cosmological modeling of these observations in
e.g. the study of the statistics of the large-scale structure of the
matter distribution in the Universe and related cosmological tests.
