Left: projection effects corr^{proj,   B/D} on the derived scale-length of decomposed disks for B/D = 0.25. The symbols represent the measurements while the solid lines are polynomial fits to the measurements. The plots represent the ratio between the intrinsic scale-lengths of decomposed and single disks, and R_i,   d, respectively, as a function of inclination (1 − cos(i)), for the B-band. An exponential (disk) plus a variable index Sérsic (bulge) distribution were used for image decomposition. Right: as in the left panel, but for the derived bulge-to-disk ratios, B/D. The effects are represented as differences between the intrinsic B/D of decomposed disks and bulges and those of single disks and bulges.
