Mass burned to NSE as compared to the mass above a density of 2 × 10 ⁷ g cm ⁻³ at the first DDT time for each realization in our sample. The different shapes plotted (+, ×, *, , █) correspond to different transition densities (10 ^7.1, 10 ^7.2, 10 ^7.3, 10 ^7.4, 10 ^7.5), respectively. The solid line shows the linear fit to yields produced with a DDT density of 10 ^7.1 g cm ⁻³ most closely matching the DDT density used in Townsley et al. (2009). The dashed line shows a 1:1 correlation between the NSE yield and mass above 2 × 10 ⁷ g cm ⁻³. The lowest two DDT densities are less than the density threshold 2 × 10 ⁷ g cm ⁻³ and thus show more scatter about the linear relation due to increased dependence on the plume morphology.
