Top panel and middle panel: stars of the sample in the T_eff–log g plane. Stars in the top panel are color-coded by their metallicities, and in the middle panel, stars in the effective temperature region of the Li desert are color-coded according to their Li abundance. Bottom panel: temperature distribution of the final catalog compared to the compilation of Ramírez et al. (2012), the largest sample with measured stellar ages and masses so far (R12), the new literature data obtained from Delgado Mena et al. (2014); Gonzalez (2014); Delgado Mena et al. (2015) and Gonzalez (2015) (Literature) and the new measurements provided by this work (This work). We note that, while few in relative terms, the new measurements reported in this work span, by design, the temperature region of the Li desert.
