Notes. α and δ are J2000 equatorial coordinates of the cluster centre in degrees, r is the distance to the cluster centre in pc, μα,δ is the proper motion in mas yr−1, σα,δ is the dispersion of the proper motion distribution (mas yr−1), σr is the dispersion of the radial distance distribution (pc), ρcl is a characteristic scale of the cluster in degrees, ρ1∕2 is the radius which contains half of the cluster members in degrees, log t is the logarithm of the cluster age in years, vr is the mean radial velocity of the cluster in km s−1, and σv is its standard deviation. Coordinates, proper motions, and ρ1∕2 are from Cantat-Gaudin et al. (2018), age and metallicity are from Dias et al. (2002), and radial velocities are from Soubiran et al. (2018) and Sartoretti et al. (2018).
