Using the dips estimated in the first step and the static
corrections estimated in the second step, the data are interpolated
onto whatever output geometry is desired.
Interpolation is performed by a local slant stack, using several
neighboring traces. The number of neighbors used need not be
the same as in the dip estimation case.
In doing the interpolation, it is possible to median filter
along the stacking trajectory and/or weight the output by
the semblance coefficient obtained in dip estimation
(using the semblance measured at the nearest available
location). I demonstrated Cole (1993) that median filtering
can make the interpolation less sensitive to noise bursts on isolated
traces. And the nonlinear semblance weighting can enhance coherent events.
