Reflector convergence

Reflector convergence attribute is useful in the interpretation of angular unconformities.  It is a measure of the change in reflector normal about a
more or less horizontal axis.

Time slices through a coherence volume at (left) t=2.700 s and (right) t=2.670 showing two channel system.  The channel is clearly delineated (yellow arrows) in the deeper slice (left) but not at the shallower slice (right).

The same two time slices at (left) t=2.700 s and (right) t=2.670 now co-rendered with reflector convergence. Note the change in convergence towards the edges of the channel within the deeper slice shown in (left) and away from the center of the channel in the shallower section seen in (right).
