Abstract
The permitted broad component of the Hβ emission line in the broadline radio galaxy (BLRG) 3C390.3 presents a double-peaked structure, similar to that seen in cataclysmic variables. The profile of the line is well fitted by a relativistic accretion disc with an intermediate inclination to the line-of-sight.
