Dust effects corr^sS on the derived effective radius of galaxies fitted with single Sérsic functions. The symbols represent the measurements while the solid lines are polynomial fits to the measurements. The plots represent the ratio between the effective radius of a bulge+disk system and a single disk, and R_app,d respectively, as a function of inclination (1 − cos(i)), for the B and K optical bands. The black curves are plotted for (from the bottom towards the top), while the other curves correspond to (green), 4.0 (red) and 8.0 (blue).
