cds-question@unistra.frglobular-star-clustersinfrared-photometryvisible-astronomyWide-band photometryWe present new optical observations of young massive star clusters in Arp 220, the nearest ultraluminous infrared galaxy, taken in UBVI with the Hubble Space Telescope ACS HRC camera. We find a total of 206 probable clusters whose spatial distribution is centrally concentrated toward the nucleus of Arp 220. We use model star cluster tracks to determine ages, luminosities, and masses for 14 clusters with complete UBVI indices or previously published near-infrared data. We estimate rough masses for 24 additional clusters with I<24mag from BVI indices alone.2006ApJ...641..763Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/641/763CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/372/L41 : NGC 2068/2071 protoclusters (Motte+, 2001)J/AJ/114/2381 : UBVI photometry of NGC 7252 (Miller+, 1997)J/AJ/109/960 : Young star clusters in The Antennae (Whitmore+ 1995)J/AJ/124/1418 : Radio-optical identification of star clusters (Whitmore+ 2002)J/ApJ/561/727 : BVI photometry in the Antennae galaxies (Zhang+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/641/763https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/641/763http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/641/763https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/641/763https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/641/763http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/641/763GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/641/763/table2 (ACS HRC photometry for Arp 220 star clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/641/763/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/641/763/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/641/763/table2?GETtext/xml+votable180.050000true233.738123.501870.0055555555555555566/8673https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/641/763?format=asciiOpticalInfrareddefaultJ/ApJ/641/763/table2ACS HRC photometry for Arp 220 star clustersrecnoRecord number assigned by the VizieR team.
