| 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.

| Photoelectric radial velocities. XII - The orbits of another four spectroscopic binaries in the Clube Selected Areas
Orbits are presented for four more ninth-magnitude stars of HD type K0.HD 65195, a system containing a giant star, has the unusually shortperiod of 38 days, HD 68874 has a remarkably large mass function; but nosecondary star is seen in the radial-velocity traces or in aclassification-dispersion spectrogram, although some abnormality existsin the object's narrow-band photometric properties. A possibleresolution of the difficulty is that the secondary may itself be a closebinary, so HD 68874 may be a system analogous to HR 6497 and dSerpentis.
