Far-IR fluxes at 60 μm and 100 μm as a function of hard X-rays flux. Left panel: Scatter plot for the integrated flux at 60 μm collected from the IRAS Point source catalog (i.e., F₆₀) and that in the hard X-ray band (i.e., F_HX), as listed in the 3PBC, for both Seyfert 1 and 2 galaxies (marked in black and yellow, respectively, as shown in previous figures). No clear trend or correlation is evident. Right panel: same as left plot, but computed using the far-IR flux at 100 μm (i.e., F₁₀₀).
