Same as Fig. 8 but for a population of synthetic filaments with a more extreme (and unrealistic) distribution of column density contrasts corresponding to ⟨δ_c⟩ ∼ 2.2 (see Fig. B.4) and an area filling factor A_fil ∼ 5.5%, resulting in a combined parameter A_fil ∼ 0.27. Panel b: note how the power spectrum arising from the synthetic filament population (blue curve) dominates over the power spectrum of the Aquila original image (see green dashed curve and Fig. 6). The logarithmic slope of the best power-law fit to the total power spectrum P(k)_fil + P(k)_Aquila is −2.6 (red line). Panel c: residuals between the best power-law fit and P(k)_{Aquila + fil} (red solid circles) shows a peak near k_{fil, Aquila} = 0.45 arcmin⁻¹. For this simulation, the of the residuals is 0.28.
