Reliability of the L_AGN,torus estimations using the X-CIGALE mock catalogues for sources with and without MIR bands. Top panel: Measurements of the L_AGN,torus(erg s⁻¹) parameter with and without W4 or MIPS data. The two measurements of L_AGN,torus(erg s⁻¹) are in good agreement (ρ_torus = 0.800). The dashed line presents the 1:1 relation. Middle panel: Estimated versus true values provided by the best-fit model, for L_AGN,torus(erg s⁻¹), for the three fields used in our analysis. The filled (open) symbols represent the X-XIGALE runs with (without) MIR data. The errors on the estimated values increase when the analysis lacks MIR data. The mean value of the error on log[L_AGN,torus(erg s⁻¹)] is 0.27 dex without MIR, compared to ∼0.15 dex when MIR data are used. Bottom panel: Distributions of the difference between true and estimated values, with and without MIR data. The dispersion increases when W4 or MIPS1 are absent, but the estimated L_AGN,torus(erg s⁻¹) values are still consistent with the true values.
