Ratio between the source fluxes measured in the output simulated maps (f_out) and the source fluxes from the input blob catalog (f_true) as functions of S/N at 1.2 mm (left panels) and 2 mm (right panels) in GOODS-N (upper panels) and COSMOS (lower panels). This corresponds to the effective flux boosting described in Sect. 3.3. The boxes shown for each S/N bin represent ranges between 25% and 75% of the cumulative distribution and the upper and lower bounds of error bars present 5% to 95% of the cumulative distribution (within 1σ). The width of each box corresponds to the width of the corresponding S/N_corr bin. The red dotted line shows the position of unity effective flux boosting as a reference for each plot. In addition, we use color-coded solid-filled circles to present the median flux boosting in regions with different noise levels.
