Number density plot showing lithium abundance A(Li) of the GALAH DR3 (upper panel) and AMBRE (bottom panel) stars versus [Fe/H] (colour-coded number densities have different scales on the panels). The upper Li-envelope (red line) connects the mean A(Li) of the seven most Li-rich stars (black stars) in each bin. The dark green line connects the mean A(Li) obtained with GALAH data when using only cool stars from the same T_eff range as in the AMBRE sample (green points). Coloured boxes represent super-solar metallicity open clusters with sizes of 1σ confidential intervals on [Fe/H] and A(Li)_max from Randich et al. (2020). In all the clusters shown, the Li data were obtained for early-F type stars from the hot side of the Li dip. The open circle indicates the meteoritic value.
