ICL properties: SB profile and residuals to the best fit (top panels), the ellipticity (central panel), and the PA (bottom panel) as a function of the distance from the center. The dotted and dashed lines in the top panel refer to the SB at 1σ_sky level and to the best fit model for a de Vaucouleurs profile, respectively. Red squares correspond to those points for which the isophotal analysis did not converge, and the dot-dashed line indicates the psf FWHM limit.
