Dust effects corr^B/D on the derived Sérsic index of decomposed disks, for B/D = 0.25. The solid lines are polynomial fits to the measurements. The plots represent the difference between the derived Sérsic index of decomposed and single disks, and , respectively, as a function of inclination (1 − cos(i)), for the B and K optical bands. Two variable Sérsic index functions were used for image decomposition. The curves are plotted for (black), 2.0 (green) and 4.0 (red).
