Abstract:
We present the compilation and properties of a meta-catalogue of X-ray
detected clusters of galaxies, the MCXC. This very large catalogue is
based on publicly available ROSAT All Sky Survey-based (NORAS, REFLEX,
BCS, SGP, NEP, MACS, and CIZA) and serendipitous (160SD, 400SD, SHARC,
WARPS, and EMSS) cluster catalogues. Data have been systematically
homogenised to an overdensity of 500, and duplicate entries from
overlaps between the survey areas of the individual input catalogues
are carefully handled. The MCXC comprises 1743 clusters with virtually
no duplicate entries. For each cluster the MCXC provides three
identifiers, a redshift, coordinates, membership in the original
catalogue, and standardised 0.1-2.4keV band luminosity L_500_, total
mass M_500_, and radius R_500_. The meta-catalogue additionally
furnishes information on overlaps between the input catalogues and the
luminosity ratios when measurements from different surveys are
available, and gives notes on individual objects.
