Fig. 8


4000 Å break vs. X-ray to optical flux ratio for the normal Sy2 (red symbols) and the unobscured Sy2 (blue symbols). Dilution may be able to explain the absence of observed BEL, if they are weak, for galaxy dominated spectra (i.e. Dn> 20%; black line) with smaller contrast than usual between the AGN and the galaxy light (i.e. fX/fopt< 0.1).
