Fractional difference between parameters derived from CIGALE and the simulated ones as a function of frac_AGN, i.e. the contribution of the AGN light to the overall IR luminosity. The first column of panels plots the fractional difference in stellar mass estimates. The second column is for SFR estimates and the third column corresponds to frac_AGN. The fourth column of panels shows the distribution of . Each row corresponds to a set of simulations that assume different input SEDs for the AGN component. From top to bottom, we present results for Type-1 AGN, intermediate-type and Type-2 AGN. Different colours in each panel correspond to different functional forms for the SFH. Black is for the 2τ-dec model, green corresponds to the 1τ-dec model, and purple marks the delayed SFH. Dots represent the mean value of the fractional difference at each input frac_AGN, and the shaded regions show the one σ scatter.
