Astrophys. Suppl. Ser. 136 307 1999 1999A&AS..136..307A Clusters, open Magnitudes, photographic Positional data Proper motions astrometry catalogs methods: data analysis open clusters and associations: individual (Coma cluster) A catalogue of stellar positions and proper motions down to the 14th photographic magnitude in the area of the open cluster in Coma Berenices is compiled from data of 12 different sources. The accuracy of the proper motion data is comparable to that of the Hipparcos Catalogue (Cat. <I/239>).
