Upper row: inclination dependence of the derived Sérsic index for the dusty images of thin disks fitted with Sérsic functions. Lower row: same, for the ratio between the apparent and intrinsic Sérsic effective radii, and respectively. The symbols represent the measurements while the solid lines are polynomial fits to the measurements. From left to right, the plots corresponds to increasing UV wavelengths: 912 Å, 1500 Å, 2200 Å, and 2800 Å. The black curves are plotted for (from top to bottom, in this order for the upper row and in reverse order for the lower row). The red curve corresponds to , while the blue one is for .
