J/AZh/80/8          Proper motions of open star clusters         (Loktin+, 2003)

Proper motions of open star clusters and the rotation rate of the Galaxy. Loktin A.V., Beshenov G.V. <Astron. Zh. 80, 8 (2003)> =2003AZh....80....8L =2003ARep...47....6L
ADC_Keywords: Clusters, open; Proper motions Abstract: The mean proper motions of 390 galactic open clusters with radial-velocity measurements are computed from the data of the Tycho-2 catalog (I/259) using the kinematic and photometric cluster membership criteria. File Summary:
