Dust effects (corr^{dust,   B/D}) on the derived scale-length of decomposed disks for B/D = 0.25. The solid lines are polynomial fits to the measurements. The plots represent the ratio between the apparent scale-lengths of decomposed and single disks, and R_app,d, respectively (corrected for projection effects), as a function of inclination (1 − cos(i)), for the B and K optical bands. An exponential (disk) plus a variable index Sérsic (bulge) distribution were used for image decomposition. The black curves are plotted for , while the other curves correspond to (green), 4.0 (red) and 8.0 (blue).
