ADC_Keywords: Proper motions

Description:
    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.
