cds-question@unistra.frgalaxy-clustersgravitational-lensingWe present the results of a systematic search for gravitationally lensed arcs in clusters of galaxies located in the Hubble Space Telescope Wide Field and Planetary Camera 2 data archive. By carefully examining the images of 128 clusters we have located 12 candidate radial arcs and 104 tangential arcs, each of whose length-to-width ratio exceeds 7. In addition, 24 other radial arc candidates were identified with a length-to-width ratio of less than 7. Keck spectroscopy of 17 candidate radial arcs suggests that contamination of the radial arc sample from nonlensed objects is ~30%-50%.2005ApJ...627...32Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/627/32CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst/ : HST Archived Exposures Catalog (STScI, 2006)J/A+A/407/791 : ACO 370, 2218 and 2390 fluxes at 7 and 15um (Metcalfe+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/627/32https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/627/32http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/627/32https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/627/32https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/627/32http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/627/32GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/627/32/table3 (WFPC2 cluster catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/627/32/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/627/32/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/627/32/table3?GETtext/xml+votable180.050000true3.14125-16.46858330.005555555555555556Cone search capability for table J/ApJ/627/32/table4 (Arc list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/627/32/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/627/32/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/627/32/table4?GETtext/xml+votable180.050000true3.14078-16.46880.0055555555555555566/247 386 2310 4124 4341 4394 4867 5099 5103 5327 5536 5624 5701 5795 5828 5860 5862 5881 5915 5931 6019 6092 6337 6611 7178 7242 7345 7352 7426 7510 7516 7760 7896 7969 7970 8043 8422 8963 8969 9007 9181 9272 9466 9476 9831 9997 10169 10180 10218 10391 10422 10484 10526 10527 10664 10743 10816 10938 11042 11514 11596 11626 11672 11685 11807 12253 12359 12642 12664 16486 16609 17168 17457 17741 17767 17769 17797 17840 18041 18827 19097 19153 19542 19745 19846 19848 20384 22007 22915 22949 22970 23223 23349 26037 26189 26443 26499 26746 27136 27428 27595 27740 28126 28174 28220 28271 28622 31537 32362 32503 32739 33175 34360 35272 35759 36132 36846 40615 45826 46571 48423 49125https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/627/32?format=asciiOpticaldefaultJ/ApJ/627/32/refsReferencesrecnoRecord number assigned by the VizieR team.
