Relation of the blue continuum and the ultra-hard X-ray flux. The (noise-free) model flux at the blue end of our spectrum is plotted against the BAT 105-month ultra-hard X-ray (14–195 keV) flux. No relation between the two fluxes is seen, providing further evidence that the blue continuum in our spectra is not dominated by AGN light. The uncertainties of the BAT fluxes are within the symbol size.
