cds-question@unistra.frgalaxy-clustersx-ray-sourcesWe present the X-ray characteristics of a sample of 368 clusters of galaxies with redshifts less than 0.2 observed with the Einstein Imaging Proportional Counter. For each cluster, we measure the 0.5-4.5keV counting rate and compute the 0.5-4.5keV source luminosity, as well as the bolometric luminosity within fixed metric radii. We detect 85% of Abell clusters with z<0.1, demonstrating that the large majority of these optically selected clusters are not the results of chance superpositions. For 163 clusters, we measure their X-ray surface brightness profiles and determine their core radii. For {~}230 clusters, we then use either our measured core radii and values, or mean values derived for this sample, to measure central gas densities and gas masses. We use estimated or measured cluster gas temperatures, along with the derived gas-density profiles, to estimate total cluster masses, under the assumptions that the gas is isothermal and in hydrostatic equilibrium.1999ApJ...511...65Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/511/65CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/4 : Abell and Zwicky Clusters of Galaxies (Abell+ 1974)VII/110 : Rich Clusters of Galaxies (Abell+ 1989)VII/165 : Catalogue of measured redshifts of Abell clusters of galaxiesIX/18 : EINSTEIN extended source survey (EXSS) (Oppenheimer+ 1997)J/A+A/278/379 : X-ray Emission from Abell Clusters of Galaxies (Briel+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/511/65https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/511/65http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/511/65https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/511/65https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/511/65http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/511/65GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/511/65/table3 (Cluster properties from the Einstein survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/511/65/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/511/65/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/511/65/table3?GETtext/xml+votable180.050000true1.35463216.2261190.005555555555555556Einstein6/50 87 206 207 242 489 986 1006 1466 1701 1852 2164 2388 2414 2432 3073 4180 4203 4206 4245 4339 4341 4394 4438 4990 5005 5030 5332 5352 5618 5701 5982 6002 6335 6337 6611 6619 6768 6951 7011 7026 7329 7354 7551 7579 7614 7615 7633 7711 7754 7759 7768 7814 7883 7888 7967 7975 8220 8258 8264 8266 8268 8270 8271 8412 8442 8515 8520 8526 8575 8648 8663 8735 8749 8788 8963 8970 9009 9021 9036 9040 9048 9050 9052 9088 9101 9254 9261 9287 9333 9354 9368 9403 9443 9468 9471 9504 9506 9531 9776 10137 10235 10271 10312 10379 10404 10416 10435 10664 10716 10899 11132 11195 11213 11234 11259 11306 11419 11591 11615 11626 11628 11638 11795 11809 11818 11846 11907 11932 12006 12009 12118 12121 12642 13564 13695 14744 15112 16031 16056 16057 16075 16096 16098 16120 16409 16411 16541 16693 16696 16697 16713 16878 16926 16948 16952 16953 17029 17058 17141 17186 17237 17247 17286 17300 17504 17571 17662 17890 17952 18009 18016 18113 18168 18184 18272 18365 18411 18515 18566 18596 18607 18622 18625 18683 18953 19088 19094 19140 19170 19383 19608 19700 19783 19797 19798 19904 19905 19912 19925 19935 19993 20035 20082 20083 20282 20302 20308 20355 20481 20707 21039 21134 21156 21387 21766 22374 22577 22642 22709 22968 22969 22972 23027 23134 23393 23451 24041 24853 24912 24943 24951 24954 25042 25135 25302 25516 25520 25654 25669 25682 25852 25897 25982 26054 26109 26189 26200 26208 26313 26432 26451 26563 26770 26783 26866 26903 26906 26963 27174 27208 27224 27391 27486 27554 27586 27595 27652 27803 27825 27862 27962 27966 28172 28237 28249 28294 28371 28372 28383 28414 28415 28423 28430 28467 28471 30946 31398 31465 31509 31515 31537 31635 32894 33227 33235 33368 33628 33648 33649 33955 34181 34446 34805 35055 35659 35987 36017 36062 36070 36144 36277 36453 36573 36661 36780 37550 38814 38853 38919 39077 39079 40777 40809 43339 43626 43828 43836 43837 43877 43939 43948 43950 43977 44554 44616 44645 44650 44694 45636 45754 45984 46101 46441 46471 46484 46552 46855 46911 47595 48132 48344 48346 48360 48447 48489 48490 48519 48524 48735https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/511/65?format=asciiX-raydefaultJ/ApJ/511/65/table3Cluster properties from the Einstein surveyl_XLumLimit on Xlummeta.code.errorcharrecnoRecord number assigned by the VizieR team.
