The theory of `T-X-Y` prediction filtering can be found in
Claerbout 1994. Abma 1995
applies the `T-X-Y` prediction-error filter to signal/noise separation.
The algorithm used in this paper is the same as the one in Abma's thesis.
Here, I show three examples of the application of `T-X-Y`
prediction filtering to two synthetic CMP gathers and one real CMP gather.
