Radial velocities. Measurements of 2800 B2-F5 stars for HIPPARCOS Radial velocities have been determined for a sample of 2930 B2-F5 stars,95% observed by the Hipparcos satellite in the north hemisphere and 80%without reliable radial velocity up to now. Observations were obtainedat the Observatoire de Haute Provence with a dispersion of 80Ä,mm(-1) with the aim of studying stellar and galactic dynamics.Radial velocities have been measured by correlation with templates ofthe same spectral class. The mean obtained precision is 3.0 km s(-1)with three observations. A new MK spectral classification is estimatedfor all stars. Based on observations made at the Haute ProvenceObservatory, France and on data from The Hipparcos Catalogue, ESA.Tables 4, 5 and 6 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr or viahttp://cdsweb.u-strasbg.fr/Abstract.htm
| Mesures de vitesses radiales. VIII. Accompagnement AU sol DU programme d'observation DU satellite HIPPARCOS We publish 1879 radial velocities of stars distributed in 105 fields of4^{\circ} \times 4^{\circ}. We continue the PPO series \cite[(Fehrenbachet al. 1987;]{Feh87} \cite[Duflot et al. 1990, 1992 and 1995),]{Du90}using the Fehrenbach objective prism method.

| An investigation of the stellar association containing the 1.95 day Cepheid SU Cassiopeiae The results of photometric and spectroscopic observations of SU Cas andthe surrounding dust complex are reported. UBV photometry was made ofearly type stars in the dust complex on eight nights in 1978-79 and afurther 10 stars were surveyed within 7 arcmin of SU Cas. Spectroscopicmeasurements were also made of the objects in order to obtain radialvelocities and equivalent widths. The data suggest the region has amoving cluster (BA association) 30 pc in angular extent, with the 1.95arcday Cepheid SU Cas as a member. The association is 255-261 pc distantand has a 6 pc spread between members. The association stars are around120 Myr old, typical of 4 solar mass stars. Finally, the core membersinclude visual and spectroscopic binary system and a short-periodCepheid.
| H-beta photometry of northern intermediate galactic latitude early-type stars and galactic structure away from the plane Photoelectric H-beta photometry is presented for 255 early-type stars atintermediate galactic latitudes. Absolute magnitudes and distances arederived for the more luminous stars. Those with visual magnitudes lessthan or equal to 2.5 and at distances of up to 1 kpc from the galacticplane may follow the spiral structure in the plane.
