A(Li) vs. [Fe/H] in the shape of a scatter plot and a 2D-Gaussian kernel density plot of the MMR subgroups (from 6 to 10) in order of increasing ⟨[Fe/H]⟩. Round and inverted-triangle markers depict, respectively, LiD and LiUL measurements. The 2D-kernel densities are either in the same colour as the scatter markers (for LiD) or in grey (for LiUL). 2D-kernel densities are not shown for subgroups 9 and 10 in the case of LiD due to the low number of stars with detected Li in each of these subgroups (two and one, respectively). As in Fig. 1, additional markers were added to depict both the meteoritic and solar photospheric A(Li). The MMR group colours are the same as in Dantas et al. (2022). The errors are omitted to ease the visualisation. The median ages of each MMR subgroup are depicted at the top of each subplot; it is worth noting that subgroup 10 (purple) has a smaller t̄ than depicted in Dantas et al. (2022). The reason for this difference is due to the removal of stars with missing Li measurements.
