Best fit for the radio-γ response at 15 GHz for β_exp = 0.001 (top panel) and at 15 GHz for β_exp = 0.084 (bottom panel), and t_exp = 1 × 10⁷ s. All other parameters are the same as reported in Table 2. The light curves are in the observer frame. The red dashed line represents the actual fit interval, the orange line represents the simulated γ-ray light curve, the green line the simulated radio light curve, and the blue line is the best fit of the radio light curve obtained from the convolution of the γ-ray light curve with the best-fit response. The γ-ray light curve is the same in both panels, and appears different due to the different duration of the simulations.
