Radial velocities in the direction of the cluster NGC 2287
Mean radial velocities for 72 stars in the direction of NGC 2287 havebeen determined based on 10 plates obtained with the 40-cm ObjectivePrism of the La Silla ESO. The radial velocities are given in the IAUsystem with an accuracy of + or - 5 km/s. It is found that the peculiarstar HD 49022 is variable and has an amplitude of 70 km/s. The generalvelocity diagram has a maximum at about 22 km/s which may represent amixture of cluster and field stars and an asymmetry at 30 km/s which maybe attributed to binary member stars.
