One of several reflection events produced by the same curved or discontinuous reflector observed at the same point. Coherent reflections may be seen from different portions of the same reflector where synclinal curvature produces buried-focus effects (q.v.); see Figure B-11. Time branches due to curvature in the plane of the seismic line migrate into a syncline if the proper velocities are used, but not if there is curvature perpendicular to the line.
