by the abscissa equal to 5 km which is due to the influence of the western 

 non-horizontal contact. At the same time, the degree of variation in the 

 configuration of the 12 and 16i3m isolines brought about by this lowering 

 beneath VEP point No. 464 may be mistakenly ascribed to the result of the 

 influence of the eastern non-horizontal contact as a result of which the 

 right-hand branch of the VEP curve should be corrected in the direction 

 of a decrease in q^^. The analysis of the maximum deviations of Qi^ of VEP
