The slowness is a scalar function that depends on coordinates x and y. However, we can hold y constant and consider the curve that gives the variation of slowness with x alone.
Webslowness computed in this way may be slower than the true formation shear slowness, hence the need for a dispersion correction. The size of a correction depends on formation and WebGenerell ist die Slowness ein Vektor, der in Ausbreitungsrichtung des Wellenstrahls weist.
