Notes. Coordinates, distances and distance modulus are extracted from Harris (1996, 2010 edition), and masses are from Baumgardt & Hilker (2018). References for the metallicity: L15 – Lapenna et al. (2015); V17 – Villanova et al. (2017); O08 – Origlia et al. (2008); C09 – Carretta et al. (2009). References for the reddening are given in the text. ( † ) A small reddening correction, based on the observed and absolute VI magnitudes, will be applied (see Sect. 4.3).
