cds-question@unistra.frgalaxy-clustersgalaxy-classification-systemsgalaxy-kinematicsWe examine relations between shape, richness, and velocity dispersion for a sample of 350 clusters of galaxies of all morphologies, including those with visible substructure. For our sample the apparent shape of clusters is correlated with velocity dispersion and Abell (1958ApJS....3..211A) richness in the sense that poor, low dispersion clusters are flatter in the mean than their richer, higher dispersion counterparts. These characteristics are also exhibited by the X-ray emitting gas. There are virtually no highly flattened clusters having high richness or high velocity dispersions in the sample. We find that the variation of richness and velocity dispersion with apparent shape is too steep to be assigned to projection effects, and conclude rich, high dispersion clusters are intrinsically more nearly spherical than poorer clusters and that two-body relaxation is probably not an effective anisotropy damping mechanism in Abell clusters.1994AJ....108....1Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/108/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/110 : Rich Clusters of Galaxies (Abell+ 1989)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/108/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/108/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/108/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/108/1https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/108/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/108/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/108/1/table1 (Cluster properties and flattenings)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/108/1/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/108/1/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/108/1/table1?GETtext/xml+votable180.050000true3.4-19.50.0055555555555555566/50 206-207 1006 1701 2172-2173 3953 4185 4341 4436 4438 4443 4990 5030 5113 5116 5288 5327 5373 5394-5395 5435 5438 5524 5535 5538 5606 5616 5653 5877 5894 5967 5974 5978-5979 5982 5988 6002 6009 6335 6609 6951 7187 7633 7639 7673 7768 8212 8220 8223 8245 8247 8258 8264 8266 8271 8442 8515 8520 8526 8648 8663 8735 8749 8757 8759 8788 8856 8859 8884 8913 8919 8926 8955 8958 8970 8973 8997 9021 9036 9038 9040 9047-9048 9050-9052 9072 9075 9088 9144 9354 9366 9368 9468 9471 9476 9504 9506 9531 9776 9992 10154 10261 10271 10311-10312 10318 10342 10360 10379 10483 10627 10716 10733 10823 10841 11003 11101 11126 11182 11197 11241 11251 11279 11591 11626 11809 11814 12121 12153 12188 15112 16411 16434 16543 16599 16638 16693 16765 16781 16806 16832 16848 16854 16953 17133 17137 17141 17237 17300 17533 17571 17623 17662 17741 17810 17983 18009 18016 18018 18028 18035 18063 18113 18168 18324 18365 18388 18411-18412 18415 18450 18566 18584 18596 18607 18622 18625 18683 18953 19204 19462 19528 19573 19608 19783 19797 19905 19912 19968 19993 20021 20066 20083 20282 20302 20308 20355 20481 20511 20706 21387 22374 22577 23027 23284 24912 24943 25021 25042 25070 25135 25410 25453 25474 25485 25520 25542 25557 25581 25595 25669 25682 25697 25852 25919 26042-26043 26109 26135 26167 26185 26189 26208 26271 26329 26397 26432 26527 26734 26783 26827 26848 26854 26903 26906 26951 26990 27060 27081 27174 27224 27238 27378 27420 27472 27486 27524 27529 27586 27595 27622 27671 27685 27736 27765 27767 27775 27777 27783 27803 27807 27824-27825 27842 27865 27886 27962 27966 28003 28005 28147 28181 28205 28249 28265 28294 28327 28345 28360 28383 28414-28415 28430 28460 28571 28598 31401 33227 33235 33638 33648-33649 33968 34443 34535 35046 35055 35360 35659 35985 36070 36453 36661 36704 37550 38853 39077 40803 40809 43627 43849 43939 43950 43977 44958 45754 45981 45984 46855 46889 48132 48447 48483 48489 48594 48639https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/108/1?format=asciiOpticaldefaultJ/AJ/108/1/table1Cluster properties and flatteningsrecnoRecord number assigned by the VizieR team.
