Plot of photon compactness as a function of time for various components. Absorbed and unabsorbed γ-rays are plotted with solid and dashed lines, respectively, while soft photons are shown with a dotted line. Parameters used for this plot: ϵ_max = 2.3 × 10⁵, ϵ_min = 23, Γ = 1.5, B = 40 G, R = 3 × 10¹⁶ cm, ℓ_inj = 1.7 × 10^-3 ≳ ℓ_γ,cr, G = 10, and τ_c = 20.
