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.

Radial velocities of faint stars from objective prism plates
A simple method by which the approximate radial velocity of a star maybe obtained from objective prism plates is described in detail. Themethod has been used to derive the velocities of 41 faint stars, most ofwhich have metal-weak spectra and are shown to be high-velocity objects.It is shown that this method may be generalized so that the radialvelocities for all measurable stars on an objective prism plate can beobtained.
