Comparison of empirical [X/Fe]_Ia yields with yields predicted from models of Ia SNe. The empirical yields are shown with filled black circles. Yields predicted from near-M_Ch models of Leung & Nomoto (2018, LN18) and Seitenzahl et al. (2013, S13) are plotted with blue symbols and yields calculated from sub-M_Ch models of Gronow et al. (2021, G21) with red symbols. The core masses and masses of the He envelope for the sub-M_Ch models are given in units of the mass of the Sun. For each model, the reduced chi-square for comparison with the empirical yields is given.
