BVRI Photometry of nz Gem, HD 73017, HD 77247, RT Vir and 104 Her
We examined single channel differential BVRI photometry of the coolstars NZ Gem, HD 73017, HD 77247, RT Vir and 104 Her obtained by thefirst author with the Four College Automated Photoelectric Telescopewith of order 100 observations taken over two or more years. Four ofthese stars are Small-Amplitude Red Variables (SARVs). The primaryperiod of NZ Gem (M3 II-IIIs) is about 33.70 days. HD 77247, theshortest period barium star with spectral type K0, has a photometricperiod of about 82 days which is close to its binary period of 80.53days. Its check star HD 73017, a non-variable in B, V and R, is variablein I due most likely to a previously unknown cooler companion. RT Vir(M8 III) is found to be a multiperiodic star whose observations areconsistent with the 155 day primary period of Lebzelter & Hinkle(2002). 104 Her (M3 III) is also multiperiodic with a primary period of21.48 days.

Spectral Classification of Stars in A Supplement to the Bright Star Catalogue
MK spectral types are given for about 584 stars in A Supplement to theBright Star Catalogue. These are compared with Hipparcos parallaxes tocheck the reliability of those classifications. The estimated errors are+/-1.2 subtypes, and 10% of the luminosity classes may be wrong.

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.
