Relative biases (see Eq. (12) in the text) given by the different detection methods and displayed against the three different ICL profile parameters (half-light radius r_e, input ICL fraction , and redshift z). The biases have been computed for each of the 270 ICL+NOISE MegaCam-type images, and the displayed values correspond to the average of the ten images with the same input parameters. The error bars correspond to standard deviations in ten different clusters. Here the values for the PF method give the amount of ICL flux lost below the 3σ detection limit (also see Fig. 2).
