Abstract
From large-offset PP seismic reflections one can estimate three traveltime parameters: the zero-offset two-way traveltime, the NMO velocity and a heterogeneity coefficient, using the shifted hyperbola approximation or a fractional approximation. From large-offset PS seismic reflections one can estimate two traveltime parameters: the zero-offset two-way traveltime and the NMO velocity.
