GAL+ICL+NOISE MegaCam-type images of nine galaxy clusters with varying surface brightness thresholds (the color bar indicates the surface brightness threshold: 26 ≤ μ_SBT ≤ 28 mag arcsec⁻²). We display here clusters with generic ICL profiles (half-light radius of r_e = 100 kpc, input ICL fraction of f_ICL = 0.4, and a redshift z = 0.1) with different ellipticities. The pixels with μ < 26 mag arcsec⁻² as well as the non-significant pixels below the detection limit are masked (e.g., white). The galaxy Sérsic profile outskirts contaminating the detection of ICL are easily discernible by eye everywhere in the image when the threshold used to mask galaxies is too bright. In the same way, part of the ICL profile is accidentally masked with galaxies when the threshold is too faint.
