| Abstract: |
Reductions of PDS microdensitometer scans of 20 plates over an epoch range of 92 years have yielded proper motions and photometry for more than 250 stars down to V about 16 in the region of the globular cluster M28 (NGC 6626). Membership probabilities for these stars, including several variables, are derived, and a color-magnitude diagram of probable members is presented and discussed. The absolute proper motion and space velocity of the cluster are derived. |
