Examples of SED fitting with CIGALE with AGN plus galaxy components. Observed and upper limit fluxes are shown in the upper part of each panel with red dots and triangles with error bars, respectively. The total model spectrum (black) in the observed-frame wavelengths, corrected for the IGM attenuation, is composed of stellar (yellow), dust, and AGN (orange) emissions. These decomposed components are shown without adding the IGM absorption model. We also report the reduced chi-square value (), fraction of AGN flux to the total emission (f_AGN) within rest-wavelengths of 0.1–0.7 μm, photometric redshift (z_phot), dust extinction coefficient (A_V), host galaxy stellar mass (M_*), and star formation rate (SFR). The lower part of each panel displays the relative residual between the data and the model. Sources that are better modeled with no AGN contribution have f_AGN ≤ 0.05, while the ones selected as quasar candidates exhibit f_AGN ≥ 0.2.
