Major- and minor-axis profiles (upper and middle rows) of simulated dust-free single disks (solid line) and of decomposed disks (dashed-line), for B/D = 0.25, in the B-band. Fits are made with an exponential function (for the disk component) and a variable-index Sérsic function (for the exponential bulge). The cuts were taken parallel and perpendicular to the major-axis of the simulated image, through their geometrical centres, at inclinations 1 − cos(i) = 0.3,0.7,0.9 (i = 46,73,84 degrees. Lower row: corresponding relative residuals () at the same inclination as the profiles. The red lines show radial and vertical cuts through the geometrical centre of the image.
