Photoelectric Vilnius Photometry of Stars in the Mega Proper Motion Field KA 10
Photoelectric seven-color photometry in the Vilnius medium-band systemis obtained for 87 stars down to V =~ 13.0 in the Kiev proper motionfield KA 10 (galactic longitude 137deg , galactic latitude--59deg . The size of the field is 1.4 square degrees. Foreach star, photometric spectral type, absolute magnitude, metallicity,and color excess due to interstellar reddening have been determined.These data, together with previous Vilnius photometry obtained in otherseven KA fields at high Galactic latitudes, will be combined withradial-velocity measurements and available proper motions to yield spacevelocities and to investigate kinematical and chemical properties of theGalactic disk in the direction perpendicular to the Galactic plane.
| Photoelectric Photometry of Herbig Ae/be and Related Stars in the Vilnius Photometric System
A catalog of photoelectric photometry of 62 Herbig Ae/Be and relatedstars in the Vilnius system is presented. It contains stars down to V =12 mag located mainly in the northern hemisphere and observed in theperiod of 1994--1996.
| Classification of Population II Stars in the Vilnius Photometric System. II. Results
The results of photometric classification of 848 true and suspectedPopulation II stars, some of which were found to belong to Population I,are presented. The stars were classified using a new calibrationdescribed in Paper I (Bartkevicius & Lazauskaite 1996). We combinethese results with our results from Paper I and discuss in greaterdetail the following groups of stars: UU Herculis-type stars and otherhigh-galactic-latitude supergiants, field red horizontal-branch stars,metal-deficient visual binaries, metal-deficient subgiants, stars fromthe Catalogue of Metal-deficient F--M Stars Classified Photometrically(MDPH; Bartkevicius 1993) and stars from one of the HIPPARCOS programs(Bartkevicius 1994a). It is confirmed that high galactic latitudesupergiants from the Bartaya (1979) catalog are giants or even dwarfs.Some stars, identified by Rose (1985) and Tautvaisiene (1996a) as fieldRHB stars, appear to be ordinary giants according to our classification.Some of the visual binaries studied can be considered as physical pairs.Quite a large fraction of stars from the MDPH catalog are found to havesolar metallicity. A number of new possible UU Herculis-type stars, RHBstars and metal-deficient subgiants are identified.
| 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.

| Photometry of stars in the uvgr system
Photoelectric photometry is presented for over 400 stars using the uvgrsystem of Thuan and Gunn. Stars were selected to cover a wide range ofspectral type, luminosity class, and metallicity. A mean main sequenceis derived along with reddening curves and approximate transformationsto the UBVR system. The calibration of the standard-star sequence issignificantly improved.

| A calibration of the gnkmfu system for dwarf stars
Calibrations to R-I and Fe/H abundance have been established for Gdwarfs in the gnkmfu narrow band system. The accuracy obtained for R-Iand Fe/H is + or - 0.02 and + or - 0.15, respectively. Also, a measureof internal consistency between the narrow band indices, Res (k), hasbeen derived. A catalogue of Res (k), R-I and Fe/H, derived from thephotoelectric indices, is given for 253 G dwarfs.
