Pre-supernova mass fractions of elements heavier than iron as a function of the mass number A at a mass coordinate of 4 M⊙ for the models computed with the rate of 17O(α,γ)21Ne from Best et al. (2013, left panel) and Taggart et al. (2019, right panel). The four vertical dashed lines show the location of the s-nuclides 56Fe, 88Sr, 138Ba, and 208Pb.
