With C-wave gathers the moveout will not be symmetric and the arrival time expression is[1]

equation (5.2.5), Thomsen (2002).

The non-hyperbolic moveout coefficent tends to be small and may be ignored for large offsets. Nonhyperbolic moveout parameter tends to be positive.

The extra coefficient is defined by

Thus, the moveout equation involves odd as well as even powers of x (see Thomsen, 2002: 5;1-2).
