Light curve obtained by integrating the total synchrotron flux emitted from a simulation box with a size of [R = 8,  Z = 200] R_jet. The computation of the light curve is realized from the four different cases of jets (H, T, P and HL). The flux is integrated from t = 0 the time of the injection of the ejecta, until t ∼ 2300 R_jet/δ with δ(θ_obs = 90° ) = 0.1 in the absolute mobile frame and with ν = 1 GHz. We separate the total flux (orange) in two component: the jet (green) and the moving shock wave (blue). Movies showing the temporal evolution of the synchrotron flux map and associated light curves are available online.
