cds-question@unistra.frgalaxy-clustersgalaxiescatalogsphotometryThe Coma cluster, Abell 1656, was the target of an HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was interrupted by the ACS instrument failure in early 2007, the partially completed survey still covers ~50% of the core high-density region in Coma. Observations were performed for 25 fields that extend over a wide range of cluster-centric radii (1.75Mpc or 1{deg}) with a total coverage area of 274arcmin^2^. The majority of the fields are located near the core region of Coma (19/25 pointings) with six additional fields in the southwest region of the cluster. In this paper, we present reprocessed images and SEXTRACTOR source catalogs for our survey fields, including a detailed description of the methodology used for object detection and photometry, the subtraction of bright galaxies to measure faint underlying objects, and the use of simulations to assess the photometric accuracy and completeness of our catalogs. We also use simulations to perform aperture corrections for the SEXTRACTOR Kron magnitudes based only on the measured source flux and its half-light radius. We have performed photometry for 73,000 unique objects; approximately one-half of our detections are brighter than the 10{sigma} point-source detection limit at F814W=25.8mag(AB). The slight majority of objects (60%) are unresolved or only marginally resolved by ACS. We estimate that Coma members are 5%-10% of all source detections, which consist of a large population of unresolved compact sources (primarily globular clusters but also ultra-compact dwarf galaxies) and a wide variety of extended galaxies from a cD galaxy to dwarf low surface brightness galaxies. The red sequence of Coma member galaxies has a color-magnitude relation with a constant slope and dispersion over 9mag (-21<M_I_<-13). The initial data release for the HST-ACS Coma Treasury program was made available to the public in 2008 August. The images and catalogs described in this study relate to our second data release.2010ApJS..191..143Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/191/143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.astro-wise.org/projects/COMALS/ : HST-ACS Coma Legacy Surveyhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/191/143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/191/143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/191/143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/191/143https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/191/143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/191/143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/191/143/catalog (The full HST/ACS Coma cluster survey catalog (scale=0.05arcsec/pix))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/191/143/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/191/143/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/191/143/catalog?GETtext/xml+votable180.050000true195.1572128.058230.0055555555555555566/10378 10379 10400 10401 281272.0401237512456292e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/191/143?format=asciiOpticaldefaultJ/ApJS/191/143/catalogThe full HST/ACS Coma cluster survey catalog (scale=0.05arcsec/pix)recnoRecord number assigned by the VizieR team.
