Compared with the calculation of the operators, the application of the
operators to migrated images is relatively simple. Let us take residual
depth migration of post-stacked depth image as an example. We have the
following algorithm:
`Loop over surface location` *x*_{c}

`Loop over output image location` (*x*,*z*)

.

Here the amplitudes of the operators are set to be constant. It is possible
to compute more correct amplitudes of the operators with WKBJ approximation.
