cds-question@unistra.frgalaxy-clustersgalaxiesphotometryspectroscopyThe influence of environment on the formation and evolution of early-type galaxies is, as yet, an unresolved issue. Constraints can be placed on models of early-type galaxy formation and evolution by examining their stellar populations as a function of environment. We present a catalogue of galaxies well suited to such an investigation. The magnitude-limited (b_J_<=19.45) sample was drawn from four clusters (Coma, A1139, A3558 and A930 at <z>=0.04) and their surrounds. The catalogue contains luminosities, redshifts, velocity dispersions and Lick line strengths for 416 galaxies, of which 245 are classified as early types. Luminosity-weighted ages, metallicities and {alpha}-element abundance ratios have been estimated for 219 of these early types. We also outline the steps necessary for measuring fully calibrated Lick indices and estimating the associated stellar population parameters using up-to-date methods and stellar population models. In a subsequent paper we perform a detailed study of the stellar populations of early-type galaxies in clusters and investigate the effects of environment.2010MNRAS.409.1455Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/409/1455CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/409/1455https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/409/1455http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/409/1455https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/409/1455https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/409/1455http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/409/1455GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/409/1455/catalog (Low-redshift galaxies, line-strengths and stellar population parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/409/1455/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/409/1455/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/409/1455/catalog?GETtext/xml+votable180.050000true149.2732083-2.550250.0055555555555555565/6703 6714 6789 6800-6801 10959 10980 6/10378-10379 10400-10401 26850 26860 26862 26938 27013-27014 27017 27021-27022 27024 27028 27030-27031 27033-27035 27038-27039 27045 27056-27057 27060-27061 27164 27209-27213 43823 43827 43830-43833 43835 43874 43881-43883 43924-43926 43968https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/409/1455?format=asciiOpticaldefaultJ/MNRAS/409/1455/catalogLow-redshift galaxies, line-strengths and stellar population parametersrecnoRecord number assigned by the VizieR team.
