Abstract:In this paper, a modification of the well-known Sanders method for estimation of the membership probabilities for stars in stellar clusters is proposed. It is shown that adding one more normal distribution to the approximation expression for the two-dimensional probability density of proper motions allows us to obtain more reliable values for membership probabilities.
