Using our models of absorption-line indices that account for variable abundance ratios, we derive ages, total metallicities, and element ratios of 124 early-type galaxies in high- and low-density environments. The data are analyzed by comparison with mock galaxy samples created through Monte Carlo simulations taking the typical average observational errors into account, in order to eliminate artifacts caused by correlated errors.2005ApJ...621..673Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/621/673CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/395/431 : Line-strength indices for 148 early-type galaxieshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/621/673https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/621/673http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/621/673https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/621/673https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/621/673http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/621/673GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/621/673/galaxies (Line indices and population parameters of the 124 galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/621/673/galaxies?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/621/673/galaxies?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/621/673/galaxies?GETtext/xml+votable180.050000true10.674458340.86588890.0055555555555555566/2214 2251 2622 2709 5075 8173 8193 8195 8196 10377 10378 10379 10382 10400 10401 10404 11525 13128 15056 17060 17472 17520 17605 17606 17612 17662 18269 18931 18935 19506 20101 20658 22746 22826 23088 24702 24733 24913 25533 26065 26117 26125 27515 27604 27714 27719 27765 27773 27907 27936 28037 28221 28495 33954 34363 34493 34540 34883 34973 35037 35055 35928 36152 36247 36623 36785 37429 38701 38842 40165 40234 40252 40457 41423 42032 43289 43302 43712 43875 43915 44247 44629 44995 45311 45821 46038 46107 46164 46769 47253 47541 48160 48484https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/621/673?format=asciiOpticaldefaultJ/ApJ/621/673/galaxiesLine indices and population parameters of the 124 galaxiesrecnoRecord number assigned by the VizieR team.
