Dominant subset of the SED AGNs. Top: Frequency of the SED AGNs with f_AGN ≥ 0.5 (circles) or f_AGN ≥ 0.7 (squares) in mergers (filled symbols) and non-mergers (empty symbols) as a function of redshift. Uncertainties are estimated using binomial statistics. Bottom: Excess of the dominant SED AGNs in mergers. The red and orange bands display the AGN excess for the MIR and SED AGNs as a whole, respectively (Fig. 11).
