Notes. [Fe/H] values have been retrieved from Jacobson et al. (2016) and Spina et al. (2017) for all clusters, while α-element abundances have been taken from Magrini et al. (2017) or determined in this paper, as indicated. Abundance ratios derived from one star only are marked with “::”. Note that for the same clusters, [Fe/H] values were instead estimated using more stars (Spina et al. 2017).
