MT-Corrector 5

MT-Corrector allows to:

• inspect the sets of data estimations (MT curves) obtained in the course of automatic processing for the components of impedance tensor and other transfer functions;
• merge the data from different files into one curve (an inherent part of the workflow for the data acquired by some popular types of MT equipment, e.g., those manufactured by Phoenix Geophysics Ltd., Canada);
• delete separate data estimations and their groups based on various criteria (a priori information about the noise source, smoothness constraint, dispersion relations, etc.);
• add the fixed points based on of various criteria (data from adjacent MT sites, a priori information about the noise source, etc.);
• use the smoothing spline approximations of the MT curves, which allow to reach the reasonable balance between two contradictive requirements for the resulting curve: (a) to take on the values close enough to the average initial estimate at each given frequency; (b) to stay smooth;
• compare the spline curves of phase estimations with the theoretically equivalent curves constructed from the corresponding amplitude values using the dispersion relations;
• analyze the impedance tensor components in terms of: (a) imaginary and real parts; (b) phases and amplitudes; © phases and apparent resistivities;
• apply the static shift correction to the amplitude curves based on TDEM data;
• multiply the amplitude curves by an arbitrary coefficient; invert the phase values or add/subtract phase shifts multiple of 180°.
