Measurements of [Zn/Fe] in individual stars in the Local Group. Upper limits larger than [Zn/Fe] = 0.7 are excluded from the plot, as are stars with errors δ_[Zn/Fe]> 0.5. Blue circles show stars from this work on the Sculptor dSph, and light blue circles are Sculptor stars from the literature. Triangles are stars from other dwarf galaxies; included are (from highest to lowest stellar mass according to McConnachie 2012): Sagittarius stars are dark green, Sextans is green, Draco is magenta, Ursa Minor is orange, and yellow is for Carina stars. Squares are Milky way stars, where giant stars are dark gray and dwarf stars light gray. References (Number of stars): Sagittarius: Sbordone et al. (2007) (11). Sextans: Shetrone et al.
