Linearised ratios [Ca/H]corr as a function of [Mg/H] ratios for GCs with robust excess detections (this work). Cluster stars are coloured according to whether they belong to the P, I, or E components defined by the O and Na abundances. For NGC 2808 (Carretta 2015), NGC 5986 (Johnson et al. 2017a) and NGC 6404 (Johnson et al. 2019), we followed the original division into components.
