The weighted stacked image in Figure shows improvement over the stacked image in Figure . All of the events can be followed further underneath the salt edge after weighting. Events under the salt are stronger, although they now show artificial bright spots. In the ray parameter gathers, the events are stronger and more continuous. However, the shadow zones are now full of noise. It is clear that under the salt we have primarily increased the noise - there is almost no sign of real events. Overall, we see some improvement just under the salt edge, where the signal-to-noise ratio is still fairly good, but there are serious problems farther under the salt where the ratio is low. Also, even in the areas that show improvement, the artifacts are still strong.
