Abundance corrections for spectral lines of neutral atoms plotted versus metallicity at λ = 850 nm: Δ_{3D−⟨ 3D ⟩} (left column), Δ_{⟨ 3D ⟩ −1D} (middle column), and Δ_3D−1D (right column). Corrections are given at several different excitation potentials, as indicated on the right side of each row. Abundance corrections at λ = 400 nm and λ = 1600 nm (Figs. 3 and 5, respectively) are available in the online version only.
