Generalized nonhyperbolic moveout approximation |

If the reference ray happens to be horizontal, both and are
infinite, and equations 22-23 are not directly
applicable. However, one can use the same principle and match two
terms for the behavior of the traveltime at infinitely large
offsets. If the traveltime behaves as

for approaching infinity, then, matching the corresponding behavior of approximation 2, we find that
