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 RATAN-600 deep sky survey - Cooperative studies of 13h sources at Effelsberg, Zelenchukskaya, and Tonantzintla
Preliminary results are reported for a cooperative program (Mexico,Germany, USSR) to study the radio sources previously detected in the7.6-cm RATAN-600 deep-sky surveys. Flux densities have been measuredwith the 100-m Effelsberg paraboloid at wavelengths of 6 and/or 11 cmfor 19 RATAN-600 sources, and declinations have been refined for 13objects. In the survey strip, the objects common to the RATAN-600 andEffelsberg surveys have a mean flux density of about 30 mJy; theirpositions are now accurate to 3 arcsec in alpha and 9 arcsec in delta.Three-frequency radio spectra are obtained for some sources brighterthan 8 mJy. Many of the sources have been identified optically on glasscopies of the Palomar Sky Survey.
