Metallicity as a function of the age for the LMC analysed by Song et al. (2021) and Mucciarelli et al. (2021) is plotted as black points. The red star marks the position in the plot of KMHK 1762, while blue squares indicate the SC ESO121-03 and KMHK 1592. For KMHK 1762, we adopted the metal content estimated by Olszewski et al. (1991) (i.e. Fe/H = −0.91 dex).
