Differences between measured abundances in DLAs and stars as a function of [Fe/H] (top panel), [Zn/H] (middle panel) and [S/H] (bottom panel). Comparisons with Sculptor (Scl) stars are shown in pink (Zn) and purple (S), and with the Milky Way (MW) stars in light gray (Zn) and dark gray (S). Hexagons are Δ [Zn/Fe] and pentagons are Δ[S/Fe]. Only DLAsand stars that have published measurements of all three elements, Fe, S, and Zn, are included. The y-axis error bars show the quadratic sum of the errors of the means for DLAs and Scl or MW, while x-axis error bars show the size of each bin. Reference: see Fig. 2.
