Dictionary:Distortion tail

A correlation ghost. Harmonic distortion with vibroseis surface sources produces spurious correlations, especially for the second harmonic (which may be very large). This produces a distortion tail that follows the correlation for a downsweep and appears as a forerunner for an upsweep.
