Amplitudes of the PSPM operator

In Figure 1 the parameter $\bf{p}$ varies with a constant step. When examining the figure, the conclusion is that a higher range of dips is migrated toward the ends of the DMO operator. From a p_x parameter point of view, the distribution of the dips is more uniform, though for data closer to the surface (i.e. smaller values for the time impulse), even the constant $\bf{p}$ sampling shows an increased density updip.

Several methods have been proposed to calculate the amplitudes of a DMO operator (Deregowski and Rocca, 1981; Gardner and Forel, 1988; Black and Egan, 1988; Beasley and Mobley, 1988; Liner, 1989). The ultimate goal of any DMO amplitude related procedure is that the zero-offset section obtained from the constant-offset section honors the wave-equation.
