Metallicity distribution function (top) and [C/Fe], [Mg/Fe], [Si/Fe], [Ca/Fe], [Sr/Fe], [Y/Fe], [Ba/Fe], and [Eu/Fe] as a function of [Fe/H] for Sculptor. Pink points are abundance measurements, and gray arrows are upper limits. The black lines are 100 model realizations randomly chosen from the MCMC, which fits Ain, τin, Aout, A*, α, ANSM, ﹩{t}_{{\rm{\min }},{\rm{NSM}}}﹩, normSrNSM, and normYNSM, excluding the 5000 burn-in steps. The best-fit parameters from the MCMC are given in the first column of Table 3.
