Beginning of ReadMe : I/258 Pleiades positions and proper motions (Wang+, 1996) ================================================================================ High precision positions and proper motions of 441 stars in the Pleiades astrometric standard region Wang J., Chen L., Zhao J., Jiang P. <Acta Astron. Sinica, 37, 68 (1996)> =1996AcASn..37...68W =1996ChA&A..20..364W ================================================================================ ADC_Keywords: Clusters, open ; Positional data ; Proper motions Keywords: Pleiades - astrometric standard region - positions - proper motions Description: 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. The standard errors of star positions are less than +/-0.05arcsec, and the standard errors of proper motions for 90% stars in our reduction are less than +/-0.001arcsec/yr.
