Top: comparison between LTE Li abundances determined in this work and LTE Li abundances published in studies of de Laverny et al. (2003, green), Lèbre et al. (2006, blue), Luck & Heiter (2007, black), and Guiglion et al. (2016, red). We exclude the stars with upper limits for Li published in the literature, but we include our upper limits in the case of real determinations by the other studies. Middle and bottom: comparison with effective temperature and [Fe/H] values of same studies when available. For the sample of Luck & Heiter (2007), we show their photometric and spectroscopic effective temperatures and corresponding Li and [Fe/H] values (open and full black circles). Dotted lines represent a difference of 0.1 dex in Li and [Fe/H], and of 150 K in T_eff.
