1215 I/215 Tables of membership for 43 open clusters J -L Zhao K P Tian Bull. Inf. CDS 47 5 1995 1995BICDS..47....5Z Clusters, open Proper motions Relative proper motion data have been widely used to determine membership of open clusters. In view of the fact that most of data of proper motions had been obtained before Sanders' method was set up and information on membership of open clusters had been mostly published without a statistically rigorous method available, it is necessary to restudy membership of clusters from data by means of the rigorous method. 59 pieces of relative proper motion data for 43 open clusters having been collected, we, by use of the improved Sanders' method, calculate membership probabilities of all the stars for each field, based upon which individual member stars are found. Recently we have obtained proper motions and membership of open clusters of M67, NGC2286 and Orion, which are also included in this new version. All the results concerned are given in the form of catalogue.
