Scientific paper

The contribution of the standard motions (corrections of precession and equinox, solar motion, galactic rotation) are removed from the proper motions and radial velocities of 512 FK 4 and FK 4 Sup stars which have served as a basis for the determination of the standard motions. The residual motion components are searched for additional systematic constituents. A variety of significant effects is found. It is noted that some were known from previous studies. Most effects are found to contain a dependence on the distance from the galactic plane; this is especially pronounced in the stellar group velocities.
