Coudé spectroscopy has been carried out for 353 stars of spectral types B0 - A0 and V magnitudes between 6m.5 and 10m.8, selected in six regions (three northern and three southern) close to the galactic plane at the galactic longitudes 135°, 175°, 315° and 350°. The radial velocities were obtained by cross-correlating each spectrogram with a reference spectrogram giving an internal error of 1.4 km/s.
