Cl* NGC 2632 ART 314 , the SIMBAD biblio

High-precision proper motions for 257 and 296 stars in a 90x90' region centered on BD+20 2170 were obtained from seven plates taken with the 40cm refractor (f=6895mm) at Zo-Se station of Shanghai Observatory with six AC plates and the stellar positions in Russell's (1976, Ph.D. Thesis, University of Pittsburgh) catalogue, respectively. Combining with the data given by Klein-Wassink (=1927PGro...41....1K), Jones (1971), Artyukhina (=1971SoSht.172....3A), and Jones & Cudworth (=1983AJ.....88..215J), these proper motions give a sample of 924 stars in the region mentioned above. With membership probabilities estimated by an improved maximum likelihood method, a very good sample of 198 members is obtained with proper motion accuracies ranging from ±0.2 to ±5.0mas/yr, of which 60 per cent are better than ±1.0mas/yr, and the completeness nearly down to B=15.5.
