[Sr/Fe] and [Y/Fe] as a function of [Fe/H] for Sculptor (left, pink) and Draco (right, blue). Pink and blue points are abundance measurements from DEIMOS, and gray arrows are upper limits. The black line is the best-fit GCE model with NSMs supplying the r-process (the same model as in Figures 3 and 4). The gray lines are GCE models with all of the same parameters, but normSr_NSM and normY_NSM are set to 1.
