Density structure of our best-fit models. From top to bottom, maps of the gas density, the dust density, the dust density for particles of ~0.06 μm, and the dust density for particles of ~5 mm are shown. On all panels the radial and vertical τ = 1 surfaces at 0.55 μm are overlaid as well, with solid and dashed lines, respectively. The left and right panels contain the best Fe and amorphous C containing models, respectively.
