Notes. μαcosδ, μδ: average proper motions of cluster members in RA and Dec mas yr−1; ω: mean parallax of cluster members in mas; members: Numbers of cluster member stars; τ: cluster age in Myr; Av: extinction of the cluster in mag; all the above parameters were taken from CG20. Sep: cluster pairs’ spatial separation in pc; ratio: the star coincidence rate of cluster members. This Sep and ratio values were calculated in this work.
