Evidence that the proposed approach is feasible

As stated by (), the heuristic for proving that the inversion approach is feasible comprises three steps:

1.

Proving that shallow-origin FEAVO anomalies are visible in the angle domain and wave-equation methods correctly handle the deep-origin FEAVO effects in synthetic data. That was first accomplished by () and in this paper I present some improved results.

2.

Proving that the anomalies can be extracted in the angle domain. I will show that in the case of simple velocity distributions, the shape of the anomalies is described by very simple analytical formulas and I will discuss ways to extract them.

3.

Proving that the extracted anomalies can be transformed back to the initial domain, updating the guess. In particular, that the linearized downward continuation does not render FEAVO effects unrecognizable.
