ADC_Keywords: Stars, early-type ; Radial velocities Keywords: techniques: radial velocities - stars: early-type - stars: fundamental parameters Abstract: 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 obtained at the Observatoire de Haute Provence with a dispersion of 80Å/mm with the aim of studying stellar and galactic dynamics. Radial velocities have been measured by correlation with templates of the same spectral class. The mean obtained precision is 3.0km/s with three observations. A new MK spectral classification is estimated for all stars. File Summary:
