Zur Bestimmung der reflektierenden Ebene bei den seismischen Reflexionsmessungen

Summary

Approximate adjustment do not always allow the determination of the reflecting plane with the necessary accuracy. The latter may be increased by severe adjustment. One of severe systems supposes equally high seismic detectors placed in the same plane [Equation (5)]. But, on the one hand, this proved to be a protracted procedure, on the other hand, the conversion to equal highness does not seem to be simple [Equation (9)].

We reach our aim in a more simple way, if we make the measurements by employing the method of indirect observations so, that we obtain the most probable values of the coordinates belonging to the image of the shotpoint and of the propagation velocity [Equ. (10)–(14)]. From the adjustment we may calculate the mean square errors of the unknown quantities [Equ. (20)–(21)].

The approximate values needed for the adjustment we may calculate best from the lineare equations (23).
