CCD measurements of visual double stars made with the 50 CM refractor of the Nice Observatory
We present the measurements of 49 visual double stars made in 1997 withthe 50 cm refractor of the Nice Observatory (Table 1). A CCD camera wasattached to this refractor. Some new binaries discovered by Hipparcoshave been measured. The algorithm used for these measurements is basedon the adjustment of a tridimensional mathematical surface. Table 1 isalso available in electronic form at CDS viahttp://cdsweb.u-strasbg.fr/Abstract.html }
| 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.
