Scientific paper

We have inferred the intrinsic optical, UV and X-ray continuum of the obscured Seyfert nucleus of NGC 1068, using small aperture and polarized flux data to separate host galaxy contamination from reflected nuclear light. In support of popular unification models, we find it to be similar to typical type 1 Seyfert galaxy and quasar continua. The bolometric luminosity of the active nucleus is 2.2 x 1011 (frefl/0.01)-1(D/22Mpc)2 Lsun, where frefl is the fraction of nuclear flux reflected into our line of sight and D is the distance to NGC 1068.
