Since the two experiments were conducted with very similar acquisition parameters, none of the `optimal' cross-equalizing methods that I discussed in my earlier paper were useful. The simple time domain match-filtering approach was used instead.
In this approach, a filter, , is designed on a training window to map one survey, , onto the other, , minimizing the regression:
