Solution of M _NSE (red) and M ₅₆ (green) computed as a function of metallicity as compared to the ⁵⁶Ni relations from Timmes et al. (2003; blue) and Bravo et al. (2010; magenta) normalized to the average ⁵⁶Ni yield from our simulations. The dashed lines show the propagated standard deviation of the mean. The vertical dot-dashed line indicates the parameter space in which this study was performed. These results were evaluated with a fiducial transition density of 6.76 × 10 ⁶ g cm ⁻³ at Z = 1.4  Z _☉.
