Model-space weighting functions based on
equation (6) provide a robust way to
compensate for illumination problems during recursive depth migration
based on downward-continuation.
Data-space weights can be calculated either to work alone, or in
consort with model-space weights.
However they are less robust to errors caused by inadequate forward
modeling.
