Abstract
Absolute proper motions of stars with respect to galaxies obtained within the KSZ and MEGA programmes were used in the determination of spin parameters of the Hipparcos catalogue system relative to the inertial reference frame. The Kyiv part of the Bonn-Potsdam-Kyiv project "Hipparcos extragalactic link by photographic astrometry" is discussed. Solutions using bright stars, faint stars as well as the whole magnitude range of stars were found. "The faint KSZ stars" solution (ω_x_=-0.27+/-0.80mas/yr, ω_y_=+0.15+/-0.60mas/yr, ω_z_=- 1.07+/-0.80mas/yr) is considered as the most reliable and is recommended for the correction of the Hipparcos catalogue system.
