Dust effects corr^dust on the derived effective radius of disks fitted with Sérsic functions. The symbols represent the measurements while the solid lines are polynomial fits to the measurements. The plots represent the ratio between the apparent and intrinsic Sérsic effective radii, and respectively, as a function of inclination (1 − cos(i)), for B and K optical bands. From bottom to top, the curves are plotted for , and 8.0.
