Cumulative distributions of reddening, distance, stellar mass, and metallicity for GGCs in the top to bottom panels, respectively. Black curves represent the total sample (157 clusters) from the catalogue of Harris (1996, 2010 edition), and red curves are the sample from this work (51 clusters). The numbers in the panels are the p-values obtained by applying the Kolmogorov-Smirnov test to the black and red curves.
