Caption: Figure 6.
Temporal evolution of the peak energy for different models. Colors denote different models, as in Figure 2. The solid and dashed–dotted curves correspond to viewing angles of θv = 10∘ and 20∘, respectively. The black dashed line indicates the power-law decay ﹩{E}_{{\rm{peak}}}\propto {t}_{{\rm{obs}}}^{-0.6}﹩.
