Salt dome

The target here is a salt dome flank and a tangential fault. Unfortunately, the distance between depth slices is rather large and therefore the input image is hardly coherent in depth. The coherency computation is limited to depth slices, and so pre-whitening with a 1-D deconvolution in depth has little effect.
