Positions of 46 radio stars: Observations of 1984–1985 and 1989–1991

Abstract The results of observations of 46 radio stars carried out with the Repsold meridian circle of the Kyyiv University Observatory in 1984–1985 and 1989–1991 are presented. The main goal of these observations is to improve the optical positions of radio stars for determination of a relationship between the optical and VLBI reference frames. The standard errors of averaged positions in two catalogues amount to 0.2 arcsec. These results were compared with those obtained with the Bordeaux meridian circle.
