Scientific paper

Radial velocity studies of the open cluster NGC 3114 were performed by use of a 40-cm Fehrenbach objective prism. The dispersion curves for 82 A and B stars, for a sample of the 'best' 23 stars selected from the 82 stars, and for 16 G and K stars are presented, and the standard deviations are calculated. A histogram of star velocities indicates that the radial velocity of the cluster is between 0 and plus 5 km/sec, which corresponds to the value of plus 1 km/sec determined by Harris (1976).
