Mock MegaCam images of a simulated galaxy cluster at redshift z = 0.1 with different ICL light profiles (the cluster is the same as was used for Fig. 2). The concentration of the profile is controlled by the half-light radius r_e, and its amplitude is controlled by the input ICL fraction f_ICL. The green circle is the radius r_in = 350 kpc, delimiting the core of the cluster. At this redshift, it covers almost the entire image. The intensity scale is logarithmic to highlight the faint ICL halo.
