Abstract:
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).
