We derive lists of proper-motions and kinematic membership probabilities for49 open clusters and possible open clusters in the zone of the Bordeaux PM2000proper motion catalogue ($+11^{\circ}\le\delta\le+18^{\circ}$). We testdifferent parametrisations of the proper motion and position distributionfunctions and select the most successful one. In the light of those results, weanalyse some objects individually. The segregation between cluster and fieldmember stars, and the assignment of membership probabilities, is accomplishedby applying a new and fully automated method based on both parametrisations ofthe proper motion and position distribution functions, and genetic algorithmoptimization heuristics associated with a derivative-based hill climbingalgorithm for the likelihood optimization. We present a catalogue comprisingkinematic parameters and associated membership probability lists for 49 openclusters and possible open clusters in the Bordeaux PM2000 catalogue region. Wenote that this is the first determination of proper motions for five openclusters. We confirm the non-existence of two kinematic populations in theregion of 15 previously suspected non-existent objects.
