Same as Fig. 1, except for model run D and compared with data set 1. Model D1 is the model with minimum . The listed parameters are: W_ring,1 = (R_out,1−R_in,1) /R_in,1 (relative radial width of the inner component), W_gap = R_in,2−R_out,1 (radial width of the gap), R_in,i = inner radius of component i, R_out,i = outer radius of component i, h_in,i = scale height of component i at its inner radius, p_h,i = scale-height power-law index of component i, p_Σ,i = surface-density power-law index of component i, τ_i = midplane optical depth of component i at 2 μm, M_dust,i = dust mass of component i.
