Relationship between the rest-frame 6 μm luminosity contributed by AGN and the absorption-corrected, rest-frame 2–10-keV luminosity for the eFEDS–W4 sample. The best-fit linear function in log–log space and its 1er dispersion are shown as the solid blue line and the shaded blue band, respectively. The cyan line represents the best-fit for an X-ray-selected AGN sample from the BUXS catalog (Mateos et al. 2015). The orange and magenta lines show two-dimensional polynomial and bilinear relations from Stern (2015) and Chen et al. (2017), respectively. The green stars represent the eFEDS–W4-nonX subsample used for the X-ray stacking analysis in which we obtained the weighted mean and standard deviation in each redshift bin by taking into account the uncertainties in N_H (N_H = 0–10²³ cm⁻²). The black dotted line represents a one-to-one correspondence between the 6 μm and 2–10 keV luminosities. The yellow star denotes the ELIRG (WISEJ0909+0002) reported in Toba et al. (2021b).
