IQR[O/Na] ratios for NGC 4833 (star symbol) and other Galactic GCs as a function of the total cluster absolute magnitude MV (left panel). The other clusters are ω Cen (filled square, Johnson and Pilachowski 2010), M 54 (filled triangle, Carretta et al. 2010b), and other GCs from our FLAMES survey (filled circles, Carretta et al. 2009a, 2011, 2013b). In the right panel the IQR[O/Na] is shown as a function of the maximum temperature on the horizontal branch, from Recio-Blanco et al. (2006). In each panel, the Spearman rank correlation coefficient (rs) and the Pearson’s correlation coefficient (rp) are reported.
