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.

The Case low-dispersion Northern Sky Survey. VI - A-F stars in a region near the north Galactic pole
Both Population I and horizontal-branch stars are included in thepresent data for the positions, estimated magnitudes, and finding chartsof 183 A-F stars in the region between RA 12 and 13 h and declinationbetween + 29 and + 34 deg. Most of the variable stars are of the RRLyrae type. The spectral category results obtained show a typicaldivision between category IV (46 percent) and category V (39 percent).Intermediate classifications comprise 15 percent.

Lists of photometric AM candidates
The Geneva photometric m parameter (Nicolet and Cramer, 1982) is used inorder to select Am photometric candidates from the Rufener (1981)catalogue. Two lists are given, the first containing field stars and thesecond cluster stars. According to the photometric criteria thediffusion process probably responsible for the Am phenomenon takes placerather quickly as Am candidates are present in young clusters. It isconfirmed that the phenomenon is enhanced by low rotational velocity andhigh metallicity. The age seems to slightly affect the Am phenomenon.

Polarization measurements and extinction near the north galactic pole
Polarimetric observations of 14 stars near the north galactic pole (NGP)are presented. The results are combined with previous measurements of 56additional stars in order to determine a lower limit to the interstellarextinction in the NGP region. It is shown that the general interstellarextinction near the NGP is at least about 0.03 mag and that there is acloud or cloud complex with interstellar extinction of at least about0.1 mag in the quadrant between galactic longitudes of 270 and 360 deg.The results also indicate that areas of higher polarization (i.e., moredust) apparently coincide with areas of denser neutral hydrogen, thatelongated H I structures are generally parallel to the galactic magneticfield in the NGP region, and that the ratio of H I column density tovisual extinction in the cited cloud or cloud complex is normal relativeto the general value in the Galaxy.

UBVRI photometry of 225 AM stars
UBVRI photometry of 225 Am stars taken from Mendoza's (1974) catalog ispresented. The results are compared with those obtained by Feinstein(1974) for 21 of the stars and with the values of Johnson et al. (1966).It is assumed that in the first approximation the (V-I) color index ofan unreddened Am star is equal to that of a normal main-sequence star; astandard main sequence is defined for A and early F stars, and thefive-color photometry is analyzed by means of plots of U-V vs. V-I, B-Vvs. V-I, and V-R vs. V-I. Mean color deficiencies of Am stars areexamined, and it is suggested that an unreddened star located below themain-sequence A0-F2 line in the (V-I, U-V) plane is a photometric Amstar. It is concluded that: (1) photometric Am stars have colordeficiencies (as a function of V-I) which, on the average, are 0.07 magin (U-V) color index and 0.025 mag in (B-V) color index; (2) Am starswith V-R less than 0.25 mag may also have a color deficiency of about0.01 mag; (3) Am stars with V-R greater than 0.3 mag may have a colorexcess of approximately 0.01 mag; and (4) Am stars with V-R between 0.25and 0.3 mag may have normal colors.
