On the systematic errors of declinations and proper motions from the Belgrade Zenith-Telescope observations in the period 1960 - 1985.

The author prepared the results of the observations with Belgrade ZT made in the period 1960 - 1985 in a computer-readable form in order to make their new reduction in the FK5 reference frame. Positions and proper motions of the stars were taken from PPM Star Catalogue. The results of determination of the systematic errors of declinations and proper motions of subgroups and Talcott's pairs in that period are presented.
