Major- and minor-axis profiles of dustless galaxies (upper and middle rows) with 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). Solid and dashed curves are for simulations and corresponding fits, respectively. The cuts were taken parallel and perpendicular to the major-axis of the simulated image, through the intensity peak, at inclinations 1 − cos(i) = 0.3,0.7,0.9 (i = 46°,73°,84°). 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.
