Notes. Columns 3-5 list the number of stars per cluster, the number of radial velocities, and the final number of radial velocities after applying the selection criteria, including the radial velocity uncertainty cut at 1 km s−1 and sigma-clipping of the radial velocity distribution. Clusters that underwent sigma-clipping are marked with an asterisk (*). See Sect. 2 for details. Columns 6-8 list the median and median absolute deviation (MAD) of each cluster’s position in heliocentric Galactic Cartesian coordinates. The distance to each cluster is given in column 8 and is sourced directly from R23a. Columns 10-12 list the median and MAD of each velocity component in heliocentric Galactic Cartesian coordinates. The cluster ages estimated by R23b are given in column 13.
