Effect of dust and disk parameters on model SED at distance 140 pc and inclination 45°. The thick full black line is the reference model (identical in every part figure), whereas the green shaded area indicates the effect of a single parameter on the SED, where the dashed and dotted lines correspond to the changed parameter values as annotated. Top row: dust mass M_dust, scale height H₀, and flaring exponent β. Second row: inner radius R_in, column density powerlaw index ϵ, and dust settling parameter α_settle. Third row: maximum grain size a_max, dust size powerlaw index a_pow, and volume ratio of amorphous carbon. The dependencies of the SED on the tapering-off radius R_tap (not shown), on the outer radius R_out (not shown), and on the minimum dust particle size a_min (not shown) are less than the one shown for ϵ.
