Membership of Stars in NGC 1039 (M34)
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-1)K colors. Cross identifications with previous surveys are also provided. We find an age for the cluster of 200-250 Myr and a distance of 475 parsecs.
