Measurements of central velocity dispersion (sigma), total B magnitudes (B_T), the photometric parameter D_n, and the absorption-line index Mgi_2 are presented. Both internal and external comparisons indicate that measurements of log{sigma} are accurate to 0.05 dex, B_T to 0.15 mag, D_n to 0.015 dex, and Mg_2 to 0.017 mag. These data have been used in a previous paper by Dressler and Faber to estimate distances for these galaxies via the D_n - {sigma} relation. It is shown in this paper that the D_n - Mg_2 relation also predicts the same trends of peculiar velocity with distance, but with less accuracy. The relative accuracy of other distance indicators for elliptical galaxies is also discussed.1991ApJ...368...54Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/368/54CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/368/54https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/368/54http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/368/54https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/368/54https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/368/54http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/368/54GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/368/54/table1catalogue of velocity, total blue magnitude, photometric diameter, velocity dispersion, and absorption-line indexrecnoRecord number assigned by the VizieR team.
