The paper suggests some objective criteria for pruning the vector point diagram, necessary when using the maximum likelihood method to calculate the membership probabilities of stars in a cluster field from their proper motions. A staggered procedure of data pruning is presented, and the determination of the distribution parameters of the two-component (cluster members and field stars) population is investigated.
