The median radius r_med of a deprojected Sérsic profile normalized by the projected semimajor axis length ﹩a^{\prime} ﹩ (solid curves) and semiminor axis length ﹩b^{\prime} ﹩ (dotted curves), as well as effective radius R_e (dashed curves), as function of the polar viewing angle ϑ. The top left panel is for the axisymmetric case with inclination i ranging from ﹩\cos i=0﹩ for edge-on (side-on) to ﹩\cos i=1﹩ for face-on (end-on) in the oblate (prolate) axisymmetric case, with intrinsic flattening q < 1 (q > 1) indicated by the different colors. The other three panels are for the triaxial case, which in addition to the polar viewing angle ϑ, also depends on the azimuthal viewing angle φ with values indicated above each panel. The intrinsic short-to-major axis ratio is fixed to q = 0.5, whereas the colors indicate different intrinsic intermediate-to-major axis ratios p.
