Radial surface-brightness profiles of all sources (blue filled dots) with their best-fit models (dotted black lines). The surface-brightness units are in mag arcsec⁻² for all the bands except for Hα (erg s⁻¹ cm⁻² arcsec⁻²). The light-blue-shaded area marks the 1σ error (for data points) and upper limits (3σ). The dotted black line indicates the best-fit model derived as described in Sect. 6.4, with its 3σ confidence level (red-shaded area). The dot-dashed green line shows the same model for an unperturbed system (without RPS). The vertical dotted red line gives the g-band effective radius of the galaxy. The vertical gray-shaded regions shown for some galaxies are the regions excluded from the model fitting, where the disk is not dominant based on the decomposition discussed in Sect. 4.5. The profiles shown here are corrected for foreground Galactic extinction and inclination.
