cds-question@unistra.frgalaxy-clustersgalaxy-kinematicsWe study the mass-to-light ratio of galaxy systems from poor groups to rich clusters and present for the first time a large database for useful comparisons with theoretical predictions. We extend a previous work, where B_j_ band luminosities and optical virial masses were analyzed for a sample of 89 clusters. Here we also consider a sample of 52 more clusters, 36 poor clusters, seven rich groups, and two catalogs, of ~500 groups each, recently identified in the Nearby Optical Galaxy sample by using two different algorithms. We obtain the blue luminosity and virial mass for all systems considered. We devote a large effort to establishing the homogeneity of the resulting values, as well as to considering comparable physical regions, i.e., those included within the virial radius.2002ApJ...569..720Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/569/720CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/569/720https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/569/720http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/569/720https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/569/720https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/569/720http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/569/720GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/569/720/table3 (Luminosity Estimates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/569/720/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/569/720/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/569/720/table3?GETtext/xml+votable180.050000true10.419167-9.3091670.0055555555555555566/50 2432 4954 5394 5618 5701 8212 8214 8220 8266 8351 8367 8442 8479 8526 8575 8648 8763 8788 8925 8938 9048 9052 9354 9443 9468 9471 9776 10172 10182 10312 10317 10379 11071 16407 16410 16411 16429 16433 16477 16492 16584 16676 16953 17137 17237 17300 17623 17630 17662 17810 17866 18016 18184 18195 18324 18584 18778 19088 20021 20355 20481 20511 20658 21134 21144 22577 23182 24943 25042 25135 25581 25769 25981 25982 26060 26422 26432 26451 26500 26510 26563 26596 26734 26848 26951 27208 27484 27595 27652 27738 27760 27803 27998 28075 28278 28414 28464 28494 28597 33234 33614 33628 33649 33756 33841 33968 34126 34440 34461 34480 34534 34703 34726 35055 35338 35530 35595 35629 35755 36048 36098 36144 36247 36704 38853 39077 39079 40294 43503 43644 43835 43838 43849 43877 43939 43950 43968 45371 45421 45542 45562 45753 45984 46101 46456 46548 46652 46911 46975 47188 47573 48171 48258 48323 48344 48456 48483 48615https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/569/720?format=asciiOpticaldefaultJ/ApJ/569/720/table2Results of Dynamical AnalysisrecnoRecord number assigned by the VizieR team.
