Use an adaptive-moving-average filter to estimate average apparent resistivities at a single static-correction-reference frequency..

The AMA filter estimates static-corrected apparent resistivities at a single reference frequency by calculating a profile of average impedances along the length of the line. Sounding curves are then shifted so that they intersect the averaged profile.

Parameters:: data (path-like object or list of pycsamt.core.edi.Edi) – Collections of EDI-objects from `pycsamt`_
Returns:: rc or z – EMAP apparent resistivity static shift corrected or static correction tensor
Return type:: np.ndarray, shape (N, M)
