Three decomposition models (B/D, B/D/bar, and B/D/bar/bl) shown for the galaxies NGC 7563 and NGC 5406. In the upper panels, the 2D representations of the surface brightness profiles are shown; black dots show the fluxes of the image pixels as a function of distance in the sky plane, and the white dots those of the total model images. The colors illustrate the fitted models of various structure components. Lower panels: r′-band mosaic images overplotted with the effective radii of the fitted models.
