Results of the photometric decomposition. Filled circles: surface brightness radial profile measured on the SDSS g-band image with the iraf task ellipse. The blue curve is the best-fitting inner disk component, the red dashed curve is the best-fitting Sérsic bulge, and the red dot-dashed curve is the outer disk component. The green curve is the sum of all the best-fitting components. Red and blue curves represent the profiles of the adopted definition for the main and secondary kinematics components, respectively.
