Here further development of the method is presented: re-calibration of the seismograms, re-interpretation of the S wave maximal amplitudes readings, a linear inversion of the (re-calibrated) amplitudes including MTs errors determination and four methods of transformation of MT errors into errors of their decomposed parts.
