[Ba/H] as a function of [Fe/H] in dSph galaxies. Sculptor is depicted with blue circles: GIRAFFE (filled); UVES (open with error bars). Literature samples for [Fe/H] ≤ −2: Sculptor in blue open circles (Shetrone et al. 2003; Geisler et al. 2005; Frebel et al. 2010; Starkenburg et al. 2013; Simon et al. 2015; Jablonka et al. 2015); Draco in red (Shetrone et al. 2001; Cohen & Huang 2009; Tsujimoto et al. 2017); Sextans in green (Tafelmeyer et al. 2010; Aoki et al. 2009); and Ursa Minor in magenta (Shetrone et al. 2001; Cohen & Huang 2010). Inverted triangles indicate upper limits. Black points are Milky Way halo stars (Burris et al. 2000; Venn et al. 2004, compilation; Barklem & Aspelund-Johansson 2005; François et al. 2007). The line is [Ba/H] = [Fe/H].
