Catalogues of declinations and proper motions of 36 Belgrade zenith stars
Using observations made with the Belgrade zenith telescope in the period1960.0-1981.0, catalogs (in three systems) of the declination and propermotions in declination of 36 zenith stars were calculated for theequinox and epoch of 1970.0. Analyses show that, relatively, the mostaccurate are the system 1 declinations (BZS1 70). The declinationsystems of the present catalogs are in good agreement with thecorresponding FK4 system. But the system of proper motions indeclination is less comparable with the FK4 system. It follows that theBelgrade zenith telescope is capable of yielding star declinations withrelatively high precision (currently about 0.22 arcsec).
