UBV absolute CCD photometry and differential astrometry of close visual double stars, with G-type primaries
We present V magnitudes, (B-V) and (U-B) colours of close visual doublestar components, and their differences as well as separations andposition angles of 40 visual double stars. The common properties of themembers of this sample are the small angular separation rho, which isless than 7'', and the common spectral type of the primaries, which areof G-type. The observations made with the Bessel U, B and V filters,while the astrometry was performed in the V filter only. For theobservations, the CCD camera attached to the Cassegrain focus of the 90cm Dutch telescope, at La Silla, Chile, had been used. From the analysisof the data we concluded that from the sample of the fourty double starsobserved seven proved to be physical pairs, while the rest must havecommon origin components. Based on observations made at ESO La Silla,Chile.

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.
