Total absolute magnitude of the detected diffuse light (F814W for the 10 Guennou et al. (2012) clusters to the left, and F160W for CL J1449+0856 to the right). The F160W filter at z = 2.07 is equivalent to the F814W filter for clusters at z ~ 0.56. Filled circles: raw values, crosses: mass normalized values with Fig. 10 of Guennou et al. (2012). Error bars are only plotted for the mass normalized values. The Guennou et al. (2012) points were assumed to be plagued by a  ± 0.2 mag error, as suggested by Fig. 10 of this paper.
