Notes.
(Marín-Franch et al. 2009, for NGC 6712 the age is taken from Paltrinieri et al. 2001).
(Harris 1996, 2010 edition).
The fraction of RHB, BHB, and EHB stars populating the HB (fRHB, fBHB, and fEHB, respectively) of each cluster have been derived from the The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters (Piotto et al. 2015; Soto et al. 2017), with the exception of ω Cen and NGC 6712, which are not part of the survey. For NGC 6712, which lacks an EHB, the RHB/BHB fractions were derived from the HB ratio presented by Paltrinieri et al. (2001), while the EHB, BHB, and RHB fractions for ω Cen were derived from Castellani et al. (2007) and Calamida et al. (2017).
