Li abundance (3D,NLTE) as a function of [Fe/H] for the N23 sample (‘Corrected-Literature’ values). We keep the same symbol notation as in Fig. 9. For the ’normal’ Plateau dwarf stars (red circles), the vertical arrows indicate Li upper limits. For the most Fe-poor dwarf, (shown with the red five-pointed star), J0023+0307, we also show the Li value determined by Aguado et al. (2019, green five-pointed star). The horizontal arrows indicate upper limits for [Fe/H]. The dashed line indicates the Spite plateau value of A(Li) = 2.3 dex used for the calibration of our models.
