Dynamical clock. The value of A+ calculated for Rup 106 and IC 4499 (red solid circles), the GC studied in Ferraro et al. (2018; black filled circles) and the Halo GCs AM1, Eridanus, Pal 3, and Pal 4 (solid star-like points) studied in Beccari et al. (2012) as a function of the logarithm of the cluster core relaxation times (trc) that have occurred since the epoch of cluster formation tGC = 12 Gyr.
