4-D cube

To compare different cross-equalization algorithms, I created two 3-D cubes based on the `Qdome' synthetic Claerbout (1994). Changes were introduced in an interval low in the section to simulate fluid movements. The two sections were the filtered by different non-zero phase filters to simulate different generations of seismic data. Finally Gaussian noise was added.

Two slices were extracted from each cube: a slice with no fluid changes to use as a design window, and a slice with fluid changes to test the success of the algorithms.
