Einfluß verbesserter Deklinationswerte auf die PZT-Breiten-bestimmungen in Potsdam (Mitteilungen des Zentralinstituts für Physik der Erde Nr. 1027)

The results of latitutde determinations with the PZT at Potsdam observatory in the years 1972–78 were used to improve the declinations of the observed stars. The latitude determinations were re-reduced with the calculated corrections of declinations in the system of the new catalog. The obtained results show a substantially better agreement and a higher stability with respect to the BIH system than the results in the system of the hitherto used star catalog.
