Shaping filers on a helix

In a helical coordinate system Claerbout (1997), calculation of shaping filters can be formulated as an autoregression. If we concatenate the two datasets being matched, and ensure that filter lags span the two datasets, then the shaping filter is identical to the prediction-filter that is used to predict the second dataset from the first. This convenient observation allows reuse of both codes and concepts.
