Absorption-corrected 2–10 keV luminosity vs. [O IV] 25.89 μm luminosity. The solid line represents the typical relation for Seyfert 2 galaxies (i.e., Compton-thin obscured AGNs) found by Liu et al. (2014). The gray shaded area shows its 1σ dispersion. Symbols and colors are the same as in Figure 3. The arrows show the 3σ upper limits when the [O IV] emission lines are not detected.
