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.

Young, high-velocity stars. I - Rotational velocities and a catalog of early-type stars at the South Galactic Pole
A catalog has been compiled of 305 early-type stars to F0 and 15thmagnitude in 218 sq deg at the South Galactic Pole. Stromgren photometryand medium- and high-resolution spectra for many of the catalog starshave been obtained. Radial velocities, H-beta line widths, Balmer jumps,and Ca II K line equivalent widths have been measured and tabulated.Rotational velocities were obtained for eight distant A stars and arefound to be typical of values for normal young main sequence stars.

Uvby-beta photometry of visual double stars - Absolute magnitudes of intrinsically bright stars
Individual absolute visual magnitudes M(v) are derived for intrinsicallybright stars and evolved stars. The results are collected for 106objects believed to be members of binary systems. uvby-beta photometrywas empirically calibrated in terms of M(v) for main sequence stars andphotoelectrically determined apparent magnitudes. The derived M(v)values are not significantly different from those stated in the Wilsoncatalogue (1976). Binary systems with main sequence primaries andsecondary components off the main sequence were also investigated.Several systems in which at least one component may be in the pre-mainsequence contraction stage are pointed out. A wide variety of commentsand derived data are given individually for 136 double stars, includingmetallicities, distance moduli, and masses.

Interstellar reddening towards the south galactic pole
B, A and F type stars are observed in an area of about 400 squaredegrees around the galactic south pole (SGP) using theStroemgren-Crawford uvby-beta system at the 60 cm telescope of theBochum station on La Silla, Chile. With calibrations for B and F typestars and the provisional calibration for the stars of Stroemgren's LateGroup-A-stars, intrinsic (b-y)0 colors are derived and then used todescribe the interstellar absorption structure of the SGP. To determinethe galactic extinction perpendicular to the galactic plane, thereddening values of distant stars are averaged in order to include boththe reddened and unreddened areas at the SGP. A mean value E(b-y)SGPequals 0.019 m is derived and is found to agree well with earliervalues, except with that of Knude (1977). Explanations for the deviationare considered, implying that Knude's value is systematically too high.

A Finding List of Stars of Spectral Type A7 and Earlier in Regions at High Galactic Latitudes. II. South Galactic Pole
An objective prism survey of stars of spectral type A7 and earlier hasbeen made of stars in a 230 square degree region at the South GalacticPole as part of an investigation of galactic structure perpendicular tothe galactic plane. The survev reported here was made with the 4°prism on the Tonantzintla Schmidt telescope and the UV prism on theMichigan Curtis Schmidt telescope at Cerro Tololo. A finding listcontaining positions and spectral types for 180 stars is presented, withfinding charts for the stars too faint to be included in the CD or BDcatalogues.
