Comparison between the total ejected mass derived from ${\overline{\mathcal{F}}}_{r_2}$ and x₁ for the cosmology sub-sample (which contains the 91T-like SNe Ia) as well as the 91bg-like SN Ia population. The black line is the line of equality. The median total ejected mass calculated from ${\overline{\mathcal{F}}}_{r_2}$ is 1.3  ±  0.3 M_⊙ and the median when calculated from x₁ is 1.2  ±  0.2 M_⊙. We find a range of 0.64–1.91 M_⊙ for M_ej for the normal SNe Ia in the cosmological sample, ignoring the single outlier at 2.24 M_⊙.
