{{#category_index:C|common-reflection-point gather, common-depth-point gather}} A collection of the seismic traces that all reflect from the same point, often corrected for normal moveout (velocity). After correcting for various possible velocities, events on the gather are horizontal when the velocities are correct. Same as depth gather. Differs from common-midpoint gather (q.v.) if there is dip or lateral velocity changes.
