Normalized light curves (left), zoom close to the light-curve maxima (center), and time-delays between each light curve and the one in the range 1–1.8 MeV (right) obtained for the first reference set of parameters. The vertical dashed line on the light curves (left) corresponds to the time when electrons reach their maximum energy γ_max and shows the moment when energy losses dominate over the acceleration at the energy γ_max.
