Comparison of progenitor mass and explosion energy among the well fitted (χ²< 3) supernova models. Colors (explosion energy) and symbols (mixing) carry the same meaning as in Fig. 9. Results are shown on the left for our recommended abundances (from Table 4) and on the right using 1D LTE abundances. To guide the eye, power-laws fitted to the low-mass and high-mass models in the left panel are shown also to the right.
