Examples of synthetic maps generated by overlaying structures (2D Gaussians, N_s = 300) on top of an fBm image with β = 2.4. The properties of the structures are randomly sampled from distribution functions of the aspect ratio (Eq. (9)), size of the major axis (Eq. (10)), and column density contrast (Eq. (11)). All models shown here share the same values of δ_c = 2.5, (L_1,min = 0.025 pc, L_1,max = 5 pc), (f_min = 3, f_max = 12), and (δ_c,min = 1, δ_c,max = 3). All syntheticmaps are convolved with a beam whose FWHM = 18.2′′.
