Main GC parameters used in this work. For each cluster we provide: ID, average reddening, E(B − V), distance module [|$(m-M)_V$|] and [Fe/H] (from the 2010 version of the Harris 1996, catalogue), cluster ages (this work), helium difference between 2G and 1G stars (⁠|$\rm \Delta \mathit{ Y}_{2G,1G}$|⁠), and maximum helium abundance variation (from Milone et al. 2018) and GC group (adapted from Milone et al. 2014, see Section 4.1).
