cds-question@unistra.frgalaxiesstellar-associationsphotometryThis paper reports on a survey of star clusters in M31 based on archival images from the Hubble Space Telescope. Paper I reported results from images obtained with the Wide Field Planetary Camera 2 (WFPC2) and this paper reports results from the Advanced Camera for Surveys (ACS). The ACS survey has yielded a total of 339 star clusters, 52 of which mostly globular clusters were found to have been catalogued previously. As for the previous survey, the luminosity function of the clusters drops steeply for absolute magnitudes fainter than M_V_=-3; the implied cluster mass function has a turnover for masses less than a few hundred solar masses. The color-integrated magnitude diagram of clusters shows three significant features: (1) a group of very red, luminous objects: the globular clusters, (2) a wide range in color for the fainter clusters, representing a considerable range in age and reddening, and (3) a maximum density of clusters centered approximately at V=21, B-V=0.30, V-I=0.50, where there are intermediate-age, intermediate-mass clusters with ages close to 500 million years and masses of about 2000 solar masses. We give a brief qualitative interpretation of the distribution of clusters in the CMDs in terms of their formation and destruction rates.2008PASP..120....1Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/120/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/48/455 : Globular Clusters in M31 and M33 (Mochejska+, 1998)J/AJ/119/727 : M31 globular clusters photometry (Barmby+, 2000)J/AJ/123/2490 : RV and [Fe/H] of M31 globular cluster system (Perrett+, 2002)J/AJ/122/2458 : M31 globular clusters from HST (Barmby+, 2001)J/ApJ/559/851 : Young star cluster candidates in M31 (Williams+, 2001)J/A+A/449/143 : Photometry of M31 globular cluster candidates (Ma+, 2006)J/A+A/456/985 : Radial velocities of 76 M31 candidate clusters (Galleti+, 2006)J/PASP/119/7 : HST WFPC2 star clusters in M31 (Krienke+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/120/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/120/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/120/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/120/1https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/120/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/120/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/120/1/table4 (New star clusters in M31)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/120/1/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/120/1/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/120/1/table4?GETtext/xml+votable180.050000true9.8900140.772650.0055555555555555566/2622-2623 2708-2709 2752https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/120/1?format=asciiOpticaldefaultJ/PASP/120/1/table4New star clusters in M31recnoRecord number assigned by the VizieR team.
