Bestimmung absoluter Eigenbewegungen in einem KSZ-Feld mit zwei Astrographen

In the field No. 153 of the KSZ program relative proper motions of 144 stars up to 15^m.0 are presented as well as parameters for the reduction to absolute with reference to 6 galaxies. The external error of one proper motion is 0.014″/y. It is shown that in a small field the statistical method for the estimation of the magnitude error is not able to give significant results due to the variance of the proper motion. It is concluded that in practice the long focus and the wide angle astrographs of the Main Observatory of the Ukrainian Academy of Science in Kiev can be combined for the derivation of proper motions.
