Comparison between input and measured fluxes of the detected galaxies matched with the IU, in the V606, H160, K_s, and IRAC CH3 simulated band. The panels show the relative errors in flux measurement, (ƒ_meas − ƒ_true)/ƒ_true, as a function of the input true magnitude; so values above zero mean over-estimation of fluxes with respect to the true values, while values below zero mean under-estimation. The color coding gives the density of sources in every point of the plots.
