Ratios of the n-capture elements to Mg. Target stars are shown with blue (GIRAFFE) and light blue (UVES) circles. The representative error bar for the Sculptor data is shown in blue. Previous measurements in Sculptor from HR spectra are shown with magenta diamonds (Shetrone et al. 2003; Geisler et al. 2005; Kirby & Cohen 2012; Skúladóttir et al. 2015a; Jablonka et al. 2015). Open diamonds are stars with peculiar abundances of the n-capture elements. Milky Way stars are shown with black squares. Open squares refer to Milky Way stars with high [Ba/Mg] >  0 and confirmed high [C/Fe] >  0.7. Milky Way references: Reddy et al. (2003, 2006) Venn et al. (2004), François et al. (2007), Mishenina et al. (2013); Roederer et al. (2014a). The SAGA database (Suda et al. 2008) was used to gather this compilation.
