Scientific paper

A list of radial velocities for 764 stars is given for three fields in the Vela-Carina region of the Galaxy. They were obtained from GPO-plates taken at La Silla and reduced following Fehrenbach's method. Slit-spectra were collected with the 152 cm-spectrographic telescope at La Silla, to derive an accurate radial velocity for a sufficient number of calibration stars: out of the 29 stars, 26 had no formerly published value. The global motions of 10 to 14 km/s can be considered as normal on the basis of galactic rotation. Some stars however show high velocities. The case of HD 81471 (Sp type A7 Iab) suggest that a detailed study of this star is to be recommended.
