from the shot pomt along the profile. 



In a case of multiple waves, the term h^ tan x- in the sum 2 f^i tan a,- hi 

 expression (5) is repeated the same numbers of times as the wave under 

 consideration passes through the ith layer.

2. The multiplier Cq is determined in the same way as for primary waves. 

 Its value is taken at the point A; = sin Uq from the curve (see Fig. 2) cor-
