Parameters of the GCs analysed in this work. The values of iron abundances, reddening, and distance modulus are taken from the 2010 version of the Harris (1996) catalogue. The average GC proper motions are derived in this paper based on Gaia EDR3 motions. Cluster age, mass at the RGB tip, RGB mass-loss, mass-loss spread, and average HB mass are derived in this paper.
