Radio lightcurves showing the result of removing various absorption/cooling effects from the model. The calculation was performed using ζ_rel = 0.15, ζ_B = 5 × 10^-5, p = 1.6, i = 60^°, and θ = 280^°. To aid comparison, the curves for “No IC” and “F(ν/ν_c) = 1” have been rescaled downwards by factors of 2 and 100, respectively. The curves for “All” and “No SSA” are closely coincident in the plots, with the latter obscuring the former.
