Spectral decomposition of the rest-frame SEDs of the target sample. The X-ray source ID (from Luo et al. 2017) and the redshift are shown in the middle-left part of each panel. The orange filled dots depict photometric data, and empty dots indicate 3σ upper limits. The black solid line is the total best-fit model, the red dotted line represents the stellar emission attenuated by dust, the AGN model is reproduced by the blue dot-dashed line, and the green dashed line accounts for dust emission heated by star formation.
