Peak line flux ratios of the gamma-ray emission from the delayed detonation (red) and the violent merger model (dashed black). The graph on the left depicts the line ratio R₁ = F(0.847   MeV)/F(2.598   MeV) of two ⁵⁶Co lines, the graph on the right illustrates the line ratio R₂ = F(0.158   MeV)/F(0.847   MeV) of a ⁵⁶Ni and a ⁵⁶Co line. The flux ratios are normalized to the optically thin limit.
