Because the model assumed in the theory of PSPM has a constant velocity, PSPM causes coherent noise from shallow scatterers to misstack, rather than stack coherently.1985, Exploration Geophysics - Volume 16, page 184:
The two far offsets misstack and are visible as a spray of energy prior in time to the stronger near offset stack response.1990, Geophysics, the Leading Edge of Exploration, page 34:

Since the CO-DMO sees a larger dip than the dip in the source-receiver direction, it overcorrects and the subsequent NMO correction will still be dip-dependent; a time shift and a misstack will occur.1996, Geophysics for Lithology Prediction, page 7:
