Investigations on Proper Motion. XXIV. Further Measures in the Pleiades Cluster.
Abstract
Five pairs of plates with intervals of about 25 years, taken at the 8O~foot focus of the 60-inch telescope in the region of the Pleiades and covering about 0.80 of a square degree, were measured for proper motion. They contain 409 stars down to photographic magnitude 15.9. Including the measures given in Mt. W. Contr. No. 653, we have measured 452 stars. Of these, 71 are found to be probable members of the Pleiades, while 9 others have motions which are of about the same order. One star may be a member of the Hyades
