Pulkovo compilation of radial velocities for 35495 stars in a common system.
Not Available
| Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.
| The color-absolute magnitude relation for E and S0 galaxies. II - New colors, magnitudes, and types for 405 galaxies
Colors and magnitudes measured in the ubVr photometric system arepresented along with galaxy types and radial velocities for 405 E, S0,SB0, and Sa field galaxies. The color-aperture effect for E and S0galaxies is investigated together with the K-reddening due to redshiftand the aperture correction to V magnitudes. An average standardcorrected color reduced to an aperture ratio of 0.5 and a standard Vmagnitude corrected to an aperture ratio of 2.5 are given for eachgalaxy; the Galactic reddening as a function of latitude is derived fromthe corrected color data. The color-absolute magnitude (C-M) relationpreviously established for the Virgo cluster and nine other nearbygroups and clusters of galaxies is shown to apply equally to the presentsample of E and S0 field galaxies. It is concluded that whatever itscause, the C-M effect appears to be universal and may be useful for thedetermination of relative distances to galaxies in clusters, groups, andthe general field.
