L1 and L2 indices as a function of the cluster age (Gyr) from VandenBerg et al. (2013), Leaman et al. (2013). The different symbols and colours identify the different cluster groups defined in Milone et al. (2014): G1 (red crosses) for metal-rich globulars ([Fe/H] > −1.0), G2 (green triangles) for clusters with [Fe/H] < −1.0 and L1 ≤ 0.4, G3 (blue circles) for globulars with L1 ≥ 0.4.
