Correlation between ﹩{M}_{\mathrm{Ej}}﹩ and ﹩{\rm{\Delta }}{M}_{15}(B)﹩ for models off the WLR (blue squares) and on the WLR (orange dots). In both cases, models with ﹩{\rm{\Delta }}{M}_{15}(B)\gt 1.55﹩ cannot be explained by ﹩{M}_{\mathrm{ch}}﹩ progenitors. Many observed SNe Ia satisfy this criterion. A linear fit to the maximum ejected mass as a function of ﹩{\rm{\Delta }}{M}_{15}(B)﹩ is shown as a red line.
