Scientific paper

It is shown through a series of calculations that the reddening law for Seyfert 1 nuclei recently proposed by Cheng et al. (1983) quantitatively accounts for the deficiency of nearly edge-on optically selected Seyferts noted in the literature. The correlation with inclination of the ratio of H-beta to hard X-ray luminosity is confirmed in the theoretical analysis. The observed distribution of values for the H-beta/hard X-ray luminosity ratio obtained by Lawrence and Elvis (1982) is compared with that predicted from the theoretical estimates.
