Light curves obtained varying Γ_c and θ_c at fixed R₀ = 10¹⁵ cm, at different viewing angles. Light curves corresponding to viewing angles θ_v = 0,  θ_c,  3θ_c are shown in blue, orange, and green, respectively. Continuous curves denote the fiducial model, with Γ_c = 100, θ_c = 3°. The structure is Gaussian and the spectrum is a SBPL function with α_s = 0.2 and β_s = 1.3. The light curves are those at ν = 10 keV normalized to the maximum value of the on-axis case and the time is relative to the time of arrival of the first photon. For better visualization, we translated the time such that the first photons arrive at 10⁻¹ s.
