cds-question@unistra.frgalaxy-clustersx-ray-sourcesredshiftedgalaxy-kinematicsWe describe the ROSAT All-Sky Survey Center for Astrophysics Loose Systems (RASSCALS), the largest X-ray and optical survey of low-mass galaxy groups to date. We draw 260 groups from the combined Center for Astrophysics and Southern Sky Redshift Surveys, covering one-quarter of the sky to a limiting Zwicky magnitude of m_z_=15.5.2000ApJ...534..114Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/534/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/518/69 : Deep Optical Catalog of galaxy systems (Mahdavi+, 1999)Table 1: Sky Coverage of the Optical Group CatalogNotes: a: First portion, excluding sections with Galactic latitude b<40{deg}b: Second portion, excluding sections with Galactic latitude b<40{deg}https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/534/114https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/534/114http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/534/114https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/534/114https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/534/114http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/534/114GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/534/114/table2 (*The RASSCALS: Basic Properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/534/114/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/534/114/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/534/114/table2?GETtext/xml+votable180.050000true2.2325-37.4708330.0055555555555555566/50 141 148 225 238 562 589 620 653 745 751 754 2215 2216 2223 2227 4209 4301 4360 4373 4410 4491 4494 4516 4519 4520 4540 4577 4691 4880 4955 4966 4990 4992 5086 5100 5192 5394 5415 5514 5640 5664 5680 5701 6500 8271 8299 8315 8339 8341 8344 8351 8357 8367 8391 8393 8419 8435 8453 8469 8521 8685 8702 8742 8750 8752 8763 8883 8891 8925 8948 9098 9219 9287 9305 9368 9429 9435 9443 9446 9464 9470 9632 9830 9883 9885 10304 10317 10342 10379 10382 10396 10397 10434 10442 10456 10471 10531 10560 10594 10627 10629 16402 16543 16599 16874 17032 17238 17274 17394 17435 17462 17492 17578 17595 17629 17662 17745 17779 17784 17866 17896 17942 17979 17998 18004 18008 18103 18123 18184 18241 18279 18302 18405 18757 18815 18884 18897 18931 18935 19143 19321 19432 19515 19900 19943 19958 19983 20072 20120 20137 20206 20208 20282 20309 20318 20320 20325 20355 20357 20372 23082 23088 24831 24839 25042 25051 25053 25054 25321 25509 25511 25610 25657 25710 25721 25769 26189 26454 26495 26563 26596 26690 26811 26884 27160 27208 27470 27486 27560 27590 27736 27738 27800 27803 27814 27874 27893 27906 28064 28075 28143 28171 28230 28249 28253 28275 28291 28321 28365 28375 28377 28414 28443 28449 28464 28476 28513 28526 28548 28597 28617 31638 31720 34578 35588 35608 35621 35623 35719 35788 35985 36036 36051 36073 36401 36648 36662 36707 36713 36736 36769 36828 43979 43995 44004 44021 44028 44587 44710 44812 46709 46855 46913 46976 46996 47021 47030 48351 48516https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/534/114?format=asciiX-rayOpticaldefaultJ/ApJ/534/114/table2*The RASSCALS: Basic PropertiesNNumber of group membersmeta.numberintrecnoRecord number assigned by the VizieR team.
