cds-question@unistra.frgalaxy-clustersx-ray-sourcessurveysWe present a 90 per cent flux-complete sample of the 201 X-ray-brightest clusters of galaxies in the northern hemisphere ({delta}>=0{deg}), at high Galactic latitudes (|b|>= 20{deg}), with measured redshifts z<=0.3 and fluxes higher than 4.4x10^-12^erg/cm^2^/s in the 0.112.4 keV band. The sample, called the ROSAT Brightest Cluster Sample (BCS), is selected from ROSAT All-Sky Survey data and is the largest X-ray-selected cluster sample compiled to date. In addition to Abell clusters, which form the bulk of the sample, the BCS also contains the X-ray-brightest Zwicky clusters and other clusters selected from their X-ray properties alone. Effort has been made to ensure the highest possible completeness of the sample and the smallest possible contamination by non-cluster X-ray sources. X-ray fluxes are computed using an algorithm tailored for the detection and characterization of X-ray emission from galaxy clusters. These fluxes are accurate to better than 15 per cent (mean 1{sigma} error).1998MNRAS.301..881Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/301/881CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)J/ApJ/502/558 : Catalog of ROSAT galaxy clusters (Vikhlinin+ 1998)J/ApJ/514/148 : ROSAT survey of bright galaxies clusters (De Grandi+, 1999)J/MNRAS/306/857 : ROSAT Brightest Cluster Sample.
