Notes. Column 1 – Names of the open clusters; Col. 2 – The number of the cluster members identified by us; Col. 3 – The number of the cluster members identified by Cantat-Gaudin & Anders (2020), with numbers in parentheses indicating the number of member stars in common with our study; Cols. 4–18 – The proper motion, RV, distance, and [Fe/H] of clusters. The med is the median of them and the columns labeled 5% and 95% are the bounds of the corresponding confidence intervals. Columns 19–21 – The age, extinction, and total stellar mass of clusters.
