Dispersions in the abundance results, in non-LTE (solid) and LTE (dashed) for dwarfs (left; log g∕cm s⁻² > 3.5) and giants (right; log g∕cm s⁻² ≤ 3.5). “Multiple obs.” (orange) show median standard deviations in [A/Fe] over multiple observations of the same stars. “Line-to-line” (blue) show the median standard deviations in [A/Fe ] over multiple spectral lines for the same star; lithium, carbon, magnesium, and potassium in red are set to zero because they were inferred from single lines. “Star-to-star” (black) show the median standard deviation in [A/Fe ] (or in log ɛ_A, in the case of lithium) across the different bins shown in Figs. 14–24.
