Partial view of Fig. B.3 (bottom), showing for metallicities [Fe/H] = 0.0 and −2.0 the difference (FFII_1DNLTE− input EW) as a function of spectrum number, now for a refined temperature grid with ΔT_eff = 100 K. For each metallicity, large, intermediate, and small dots correspond to log g = 3.5, 4.0, and 4.5, respectively. For each gravity, T_eff increases from left to right. Color coding for the temperatures of the original grid is the same as in Fig. B.3; in addition, green dots represent the results for the intermediate 1D LHD test models. As before, each effective temperature is represented by 10 dots for 1.0 ≤ A(Li) ≤ 2.8 plus a square for A(Li) = 3.0.
