Spectral index distribution (left), size-luminosity distribution (middle), and gas-dust size distribution (right) comparison between DustPy and two-pop-py at 1 Myr for a test population of substructured disks. Both test populations are constructed by sampling all combinations of the following parameters: α = 0.001, M_star = [0.3, 1.0] M_sun, M_disk = 0.01 M_star, r_c = [20, 50, 100] au, v_frag = 1000 cm/s, r_p = [0.5, 0.7] r_c, and m_p = 1 M_J.
