cds-question@unistra.frsurveysgalaxy-clustersredshiftedx-ray-sourcesWe present the revised catalog of galaxy clusters detected as extended X-ray sources in the 160 Square Degree ROSAT Survey, including spectroscopic redshifts and X-ray luminosities for 200 of the 201 members. The median redshift is z_median_=0.25, and the median X-ray luminosity is L_X,median_=4.2x10^43^h_50_^2^erg/s (0.5-2.0keV). This is the largest high-redshift sample of X-ray-selected clusters published to date. There are 73 objects at z>0.3 and 22 objects at z>0.5 drawn from a statistically complete flux-limited survey with a median object flux of 1.4x10^-13^erg/cm^2^/s. We describe the optical follow-up of these clusters with an emphasis on our spectroscopy, which has yielded 155 cluster redshifts, 110 of which are presented here for the first time. These measurements, combined with 45 from the literature and other sources, provide near-complete spectroscopic coverage for our survey. We discuss the final optical identifications for the extended X-ray sources in the survey region and compare our results to similar X-ray cluster searches.2003ApJ...594..154Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/594/154CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/594/154https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/594/154http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/594/154https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/594/154https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/594/154http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/594/154GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/594/154/table4 (160 square degree ROSAT Survey Cluster Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/594/154/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/594/154/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/594/154/table4?GETtext/xml+votable180.050000true7.63833326.3052780.0055555555555555565/2664 6/0 557 674 685 4215 4303 4341 4344 4409 4709 4831 4921 5037 5063 5091 5103 5481 5731 5804 5817 5842 5847 5850 5918 5975 6018 6038 6051 6057 6069 6073 6551 7178 7214 7296 7352 7371 7426 7576 7760 7969 7970 8053 8282 8458 8485 8528 8555 8574 8641 8767 8923 8972 9219 9242 9506 9512 9576 9632 9633 9901 10137 10169 10271 10292 10321 10422 10484 10485 10599 10694 10879 10912 10992 11029 11079 11101 11347 11514 11596 11636 11764 11795 11856 11898 11924 12241 16529 16531 16656 16671 16690 17188 17579 17749 17819 17838 17850 18212 18642 18878 19094 19151 19802 19950 19975 19990 20148 20618 21016 22721 25285 25540 25563 25585 25789 25793 25990 26100 26269 26303 26552 26563 26699 26808 27004 27060 27132 27191 27382 27664 27914 28126 28152 28185 28221 28275 28276 28356 28376 28471 28488 28517 28562 33521 33662 33713 33716 33822 33823 33866 34100 34264 34362 34520 34572 34653 35069 35240 35272 35447 35741 35758 35759 36132 36417 36526 36589 36771 43925 43947 45474 45815 45821 46079 46180 46191 46399 46459 46566 46740 48487 48500 48501 49113https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/594/154?format=asciiX-rayOpticaldefaultJ/ApJ/594/154/table4160 square degree ROSAT Survey Cluster CatalogrecnoRecord number assigned by the VizieR team.
