J/A+A/516/A3     Proper motions of PM2000 open clusters   (Krone-Martins+, 2010)

Kinematic parameters and membership probabilities of open clusters in the Bordeaux PM2000 catalogue. Krone-Martins A., Soubiran C., Ducourant C., Teixeira R., Le Campion J.F. <Astron. Astrophys. 516, A3 (2010)> =2010A&A...516A...3K
ADC_Keywords: Clusters, open ; Proper motions Keywords: open clusters and associations: general - methods: data analysis - methods: statistical - proper motions Description: We present lists of proper-motions and kinematic membership probabilities in the region of 49 open clusters or possible open clusters. The stellar proper motions were taken from the Bordeaux PM2000 catalogue. The segregation between cluster and field stars and the assignment of membership probabilities was accomplished by applying a fully automated method based on parametrisations for the probability distribution functions and genetic algorithm optimisation heuristics associated with a derivative-based hill climbing algorithm for the likelihood optimization.
