cds-question@unistra.frgalaxiesspectroscopygalaxy-kinematicsWe have derived high quality line-strength indices and velocity dispersions for a sample of 148 early-type galaxies in different environments. The wavelength region covered by the observations (lambda~4600 to 6600{AA}) includes the Lick/IDS indices Hbeta, Mg_1_, Mg_2_, Mgb, Fe5015, Fe5270, Fe5335, Fe5406, Fe5709, Fe5782, NaD, TiO_1_ and TiO_2_. The data are intended to address possible differences of the stellar populations of early-type galaxies in low- and high-density environments. This paper describes the sample properties, explains the data reduction and presents the complete list of all the measurements. Most galaxies of the sample (85%) had no previous measurements of any Lick/IDS indices and for 30% of the galaxies we present first-time determinations of their velocity dispersions. Special care is taken to identify galaxies with emission lines. We found that 62 per cent of the galaxies in the sample have emission lines, as measured by the equivalent width of the [0III]5007{AA} line, EW[OIII]~>~0.3{AA}.2002A&A...395..431Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/395/431CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/395/431https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/395/431http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/395/431https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/395/431https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/395/431http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/395/431GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/395/431/table5 (Derived accompanying properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/395/431/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/395/431/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/395/431/table5?GETtext/xml+votable180.050000true24.742917-46.5750.0055555555555555566/16480 16543 17060 17520 17605-17606 17612 20595 20658 20745 21058 21087 21106 24702 24733 24775 24839 24897 24913 26117 27186 33179 33954 34026 34161 34363 34384 34493 34521 34534-34535 34538 34540 34883 34973 35002 35037 35052 35055 35172 35621 35707 35719 35911 35928 36045 36152 36247 36472 36623 36632 36785 37267 37429 37514 37560 38699 38701 38750 38817 38822 38842 38853 38875 39176 39835 39858 39982 40165 40208 40234 40252 40294 40340 40457 41339 41343 41423 41434 42003 42030 42032 43232 43289 43302 43312 43344 43503 43608 43619 43712 43714 43835 43849 43875 43915 43924 43962 44247 44629 44812 44995 45311 45442 45469 45611 45627 45754 45756 45800 45821 46017 46036 46038 46107 46164 46566 46568 46596 46769 46987 47016 47021 47120 47181 47253 47335 47386 47411 47541 47574 48160 48464 48484 48645 48745https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/395/431?format=asciiOpticaldefaultJ/A+A/395/431/table5Derived accompanying propertiesMType?
