cds-question@unistra.frgalaxy-clustersgalaxiesphotometryccd-photometryThis paper is a continuation of an ongoing study of the evolutionary processes affecting cluster galaxies. Both CCD R band and Halpha narrow-band imaging was used to determine photometric parameters (m_r_, r_24_, Halpha flux, and equivalent width) and derive star formation rates for 227 CGCG galaxies in 8 low-redshift clusters. The galaxy sample is a subset of CGCG galaxies in an objective prism survey (OPS) of cluster galaxies for Halpha emission. It is found that detection of emission-line galaxies in the OPS is 85%, 70%, and 50% complete at the mean surface brightness values of 1.25x10^-19^, 5.19x10^-20^, and 1.76x10^-20^W/m^2^/arcsec^2^, respectively, measured within the R band isophote of 24mag/arcsec^2^ for the galaxy. The CCD data, together with matched data from a recent Halpha galaxy survey of UGC galaxies within 3000km/s, will be used for a comparative study of R band and Halpha surface photometry between cluster and field spirals.2008A&A...486..755Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/486/755CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/49 : Galaxies and Clusters of Galaxies (CGCG) (Zwicky, 1968)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/486/755https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/486/755http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/486/755https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/486/755https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/486/755http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/486/755GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/486/755/table2 (Global parameters for 227 CGCG galaxies in eight low-redshift Abell clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/486/755/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/486/755/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/486/755/table2?GETtext/xml+votable180.050000true26.147670837.6957750.0055555555555555565/425 1740 7063 7068 6/27 37 45 48 50-51 56-57 1675 1677-1679 1682 1688-1689 1699 1709 1712 1714 2257 2260-2261 2269 2346-2347 2350 2359 2401 2405-2406 2408-2409 2411-2412 2432-2433 2437 2496 4985 4989-4990 5073 5076-5077 6945 6949-6951 6957 6968-6969 10372 10374 10377-10378 10380 10383 10393-10394 10396 10398 10400-10402 10404 10413 10417 28127 28149 28241-28242 28244 28246-28247 28249-28251 28263 28276 28278 28424https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/486/755?format=asciiOpticaldefaultJ/A+A/486/755/table2Global parameters for 227 CGCG galaxies in eight low-redshift Abell clustersrecnoRecord number assigned by the VizieR team.
