Bemerkungen zur Methode der iterierten Geschwindigkeiten

Summary

The reflection segments determined by computations based on the method of images, as is well known, are lying to high for greater dips (not taking into account refraktion effects). For the case of the top layers being horizontal, the true dip of a deeper reflection segment is determined and subsequently a graphical method given enabling quick locating of the true position. For the case that, from a certain depth downward, the velocity will be constant, the angular correction can be read from a nomogram. Finally, the question is discussed when corrections will be allowed to be neglected.
