Fig. 6.
Distributions of light- (C, N), α- (Mg, Si) and odd-Z (Al) elements in different abundance planes. Panels a–d: the planes [Al/Fe]–[Mg/Fe], [N/Fe]–[C/Fe], [Al/Fe]–[Si/Fe], [Si/Fe]–[Mg/Fe] are respectively shown for GCs from Mészáros et al. (2020). The black dotted line at [A/Fe] = +0.3 indicates the generalized separation of FG and SG stars as proposed in Mészáros et al. (2020). The distributions for UKS 1 star candidates (lime squares) are overlaid.
