Overview of the Li abundance corrections Δ_3DNLTE-1DLTE (top) and Δ_1DNLTE-1DLTE (bottom) as evaluated on the complete 4D parameter grid. For each metallicity, a total of 165 points indicates the corrections as a function of an arbitrary spectrum number that runs over A(Li), T_eff, and log g. Large (left group), intermediate (middle group), and small dots (right group) correspond to log g = 3.5, 4.0, and 4.5, respectively. For each gravity, T_eff increases from left to right (5000 K: red, 5500 K: black, 5900 K: gray, 6300 K: black, 6500 K: blue). Each effective temperature is represented by 11 dots indicating the results for 1.0 ≤ A(Li) ≤ 3.0.
