Scientific paper

On the assumption that large-radii emission dominate, the present calculation of a geometrically thick accretion disk's emission-line profile neglects all general relativistic effects. A flat-topped profile is observable if the angle between the line-of-sight and the rotation axis is between a critical angle larger than the inclination of the torus' funnel wall to the rotation axis and 180 deg minus that critical angle. The critical angle decreases with increasing torus thickness.
