Same as Fig. 8 for GALAH sub-samples with high accuracy or level of confidence in NLTE Li abundance (i.e. with Flag_Cannon = 0 and Flag_Li ≤ 1) and derived stellar parameters (Gaia DR2 parallaxes with errors less than 20%, and errors on T_eff less than 150 K), and with −0.2 ≤ [Fe/H] ≤ +0.2 and [Fe/H] < −0.2 (left and right respectively). Evolution tracks are the standard models of Lagarde et al. (2012) computed with [Fe/H] = 0 (left), and [Fe/H] = 0 and −0.56 (right, dashed and solid respectively).
