Top panels: deconvolved VST r-band profiles of ETGs in FDS plotted on a logarithmic scale. The blue line indicates a fit to the outer regions. The red and magenta lines indicate a fit to the inner and middle regions with a Sérsic profile, and the black line indicates the sum of the components from each fit. The dotted line indicates the core of the galaxy, which was excluded in the fit. Bottom panels: Δ rms scatter (see text for details).
