Proper motions of open star clusters from Tycho-2 catalogue data

Beshenov, G. V.; Loktin, A. V.

The results of determinating the proper motions of open clusters on the basis of the Tycho-2 catalogue data are presented here. The resulting catalogue contains mean proper motions for 390 open clusters.

On putting the catalogues of the relative proper motions of open cluster stars in one system (cluster M67)

Loktin, A. V.

In this paper a method for putting the catalogues of the proper motions of cluster stars in one system is discussed on the base of numerical experiments. The catalogue of proper motions of stars in the field of open cluster M67 based on five catalogues of relative proper motions and the Tycho-2 catalogue is compiled.
