Capital letters A, B, C, D, BC and BD indicate types of inaccuracies in the inversion problem. In each of the types, NRMS corresponding to the MT model is in the left-hand column, NRMS for the DC model in right-hand column.

NRMS is L₂ norm of the differences of the data and the synthetics normalized by the L₂ norm of the data. The variance reduction can be calculated as 100*(1-NRMS).
