Abstract:
We have measured proper motions, positions, magnitudes, and colors for
630 stars to V∼16.2 in the vicinity of the open cluster NGC 1039=M34.
A proper motion membership probability analysis has been performed. We
give for all stars the equatorial coordinates, the proper motions, the
V magnitude, and the membership probability. For the most likely
cluster members we also give B-V and (V-I)K colors. Cross
identifications with previous surveys are also provided. We find an
age for the cluster of 200-250Myr and a distance of 475parsecs.
