Median demagnified integrated flux density as function of observed integrated flux density for A2744 (red crosses), MACS J0416 (green squares), and MACS J1149 (blue diamonds). Median values were obtained by combining all models for each cluster field. Error bars in demagnified fluxes correspond to the 16th and 84th percentiles, while for observed fluxes, there are 1σ statistical uncertainties. As a reference, black lines indicate magnification values of one (solid), five (dotted), ten (dashed), and 50 (dot-dashed).
