cds-question@unistra.frgalaxiescatalogsgalaxy-clustersx-ray-sourcesredshiftedsouth-galactic-poleA field of 1.013sr in the ROSAT All-Sky Survey (RASS), centered on the south Galactic pole (SGP), has been searched in a systematic, objective manner for clusters of galaxies. The procedure relied on a correlation of the X-ray positions and properties of ROSAT sources in the field with the distribution of galaxies in the COSMOS digitized database, which was obtained from scanning the plates of the UK Schmidt IIIa-J optical survey of the southern sky. The study used the second ROSAT survey database (RASS-2) and included several optical observing campaigns to measure cluster redshifts. The search, which is a precursor to the larger REFLEX survey encompassing the whole southern sky, reached the detection limits of both the RASS and the COSMOS data and yielded a catalog of 186 clusters in which the lowest flux is 1.5x10-12ergs/cm^2^/s in the 0.1-2.4keV band. Of these 157 have measured redshifts. Using a flux limit of 3.0x10-12ergs/cm^2^/s a complete subset of 112 clusters was obtained, of which 110 have measured redshifts. The spatial distribution of the X-ray clusters out to a redshift of 0.15 shows an extension of the Local Supercluster to the Pisces-Cetus supercluster (z<0.07), and an orthogonal structure at higher redshift (0.07<z<0.15). This result is consistent with large-scale structure suggested by optical surveys.2002ApJS..140..239Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/140/239CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (Voges+ 2000)IX/30 : Second ROSAT PSPC Catalog (ROSAT, 2000)J/ApJ/514/148 : ROSAT survey of bright galaxies clusters (De Grandi+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/140/239https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/140/239http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/140/239https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/140/239https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/140/239http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/140/239GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/140/239/table3 (Catalog of clusters in the SGP)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/140/239/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/140/239/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/140/239/table3?GETtext/xml+votable180.050000true330.460417-22.4436110.0055555555555555566/6 16387 16407 16410 16411 16434 16454 16477 16481 16486 16492 16510 16526 16540 16543 16578 16580 16599 16609 16642 16661 16681 16683 16695 16711 16713 16721 16765 16767 16782 16806 16822 16854 16924 16926 16953 16959 16965 17059 17069 17084 17124 17133 17141 17165 17237 17247 17260 17298 17300 17307 17357 17387 17389 17395 17406 17410 17438 17442 17452 17457 17464 17472 17515 17618 17623 17662 17684 17704 17712 17715 17744 17745 17784 17797 17799 17805 17810 17840 17957 17993 18011 18016 18035 18064 18079 18176 18184 18437 18566 18584 18585 18596 18622 18635 18668 18671 18683 18742 18746 18757 18800 18872 19204 19462 33748 33774 34442 34443 34490 35007 35055 35097 35121 35130 35147 35158 35171 35202 35266 35271 35325 35343 35441 35455 35536 35595 35659 35696 35719 35755 35758 35808 35835 35853 35950 35976 35985 36012 36013 36017 36023 36028 36038 36048 36070 36094 36453 36490 36521 36548 36573 36577 36582 36846 46312 46313 46350 46441 46470 46474 46484 46499 46526 46540 46548 46687 46855 46860 46868 46889 46911 46915 46952 47028 48456 48459 48479 48501https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/140/239?format=asciiX-rayOpticaldefaultJ/ApJS/140/239/table3Catalog of clusters in the SGPz?
