cds-question@unistra.frgalaxy-clustersx-ray-sourcessurveysredshiftedGalaxy clusters provide unique laboratories to study astrophysical processes on large scales and are important probes for cosmology. X-ray observations are currently the best means of detecting and characterizing galaxy clusters. Therefore X-ray surveys for galaxy clusters are one of the best ways to obtain a statistical census of the galaxy cluster population. In this paper we describe the construction of the REFLEX II galaxy cluster survey based on the southern part of the ROSAT All-Sky Survey. REFLEX II extends the REFLEX I survey by a factor of about two down to a flux limit of 1.8x10^-12^erg/s/cm^2^ (0.1-2.4keV). We describe the determination of the X-ray parameters, the process of X-ray source identification, and the construction of the survey selection function. The REFLEX II cluster sample comprises currently 915 objects. A standard selection function is derived for a lower source count limit of 20 photons in addition to the flux limit. The median redshift of the sample is z=0.102. Internal consistency checks and the comparison to several other galaxy cluster surveys imply that REFLEX II is better than 90% complete with a contamination less than 10%. With this publication we give a comprehensive statistical description of the REFLEX II survey and provide all the complementary information necessary for a proper modelling of the survey for astrophysical and cosmological applications.2013A&A...555A..30Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/555/A30CatalogResearchIsServedByTAP VizieR generic servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (Voges+ 2000)J/A+A/499/357 : REFLEX galaxies redshifts (Guzzo+, 2009)J/A+A/425/367 : REFLEX Galaxy Cluster Survey catalogue (Boehringer+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/555/A30https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/555/A30http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/555/A30https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/555/A30https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/555/A30http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/555/A30GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapX-rayOpticaldefaultJ/A+A/555/A30/table2Count rate to flux conversion (for z=0)recnoRecord number assigned by the VizieR team.
