资源简介：
Based on a preliminary reference catalogue, combined with the
catalogues PPM, ACRS and those in Eichhorn et al (1970, Cat. I/90),
Jones (1973A&AS....9..313J) and Hertzsprung (1947AnLei..19a...1H), 33
exposures on 11 plates taken with the Zo-Se 40cm refractor (f=6895mm)
in 86 years are reduced with the central overlapping technique, and
high-precision positions and proper motions of 441 stars in the
Pleiades astrometric standard region are obtained.
