Proper Motions

Scientific paper

The proper motions were derived from comparison catalogues AGK3R, KSZ. This catalogues was observed with Repsold meridian circle at Nikolaev observatory during the years 1956-65; AGK2, Yale (1928-1933) and AGK1 (1968-1905). The mean errors (M.E.) of annual proper motions are M.E.(in Mu-Alfa x cos Decl.) = +/- 0.0002-0.0003 timesec/year M.E.(in Mu-Decl.) = +/- 0.003-0.005 arcsec/year Proper motions were obtained in the FK3 system. The usage of the AGK1 catalogue allowed the author to increase the epoch differences up to 90 years and to obtain the maximum precision at the present time. (1 data file).
