Anti-crosstalk

Outlook

Many examples suggest themselves.

1. We might model reflection data as a superposition of primaries and multiples. We might model it as a superposition of pressure waves and shear waves.
2. In tomography we might model event flatness as a superposition of shallow and deep slownesses. The shallow and deep slownesses have wholly different causes separated by millions of years. They should not show crosstalk.
3. The problem of segregating signal and noise offers many examples. We'd like to see signal containing no evident noise and vice versa.
4. In time-lapse seismology we would like to see the the image change unpolluted by the original image. Unfortunately, the methodology proposed here does not allow for time-shifted crosstalk.
