Value of the present-day slope of the stellar mass function (α_pd) plotted as a function of the ratio (log(t_age/t_rh)), where t_age are the ages of the clusters and the t_h their present-day half-mass relaxation time (upper subpanel) and fraction of G1 stars in the clusters plotted as a function of log(t_age/t_rh) (lower subpanel). In both subpanels, clusters are segregated by their mass, which is taken to be the mean value of the photometric and dynamical masses.
