As in Fig. 5. Summary of the surface photometric analysis of KIG 732 (top panels). We show the B+D model. We show 20 isophote levels, between 500 and 2σ of the sky level, for the original and model images. Summary of the surface photometric analysis of KIG 733 (middle panels). Deep g and r images are shown with isophote contours down to the 2σ level of the sky. Bottom panels: the right r image enhances the central part of KIG 733, showing the ring and the arm-like structure, and the left panel shows the g and r light profiles.
