[Eu/Fe] vs [Fe/H] for Sagittarius (top panel), Fornax (central panel), and Sculptor (bottom panel). Data for are from Liberatori et al. (2025) for Sagittarius, Reichert et al. (2020) for Fornax, and Hill et al. (2019) for Sculptor. The dark shaded areas are the range of predicted values, adopting the reference MNS yield and a MNS yield that is a factor of 5 greater to account for the uncertainties in MNS yield measurements by Watson et al. (2019). The thin solid lines and light shaded areas represent the non-parametric Gaussian KDE data regressions and their 1σ confidence interval for [Eu/Fe] vs [Fe/H].
