Plot 1.5D refractors obtained with layer-based No need to map traveltimes to refractors. WET Wavepath Eikonal Traveltime inversion (Schuster, 1993). The starting model is then refined with 2D Horizontally averaging DeltatV (Wiechert-Herglotz) methodДЎD velocity-depth profiles along the seismic line. A smooth minimum-structure and artefact-free 1D starting model isДetermined automatically directly from the seismic traveltime data by Increases the numerical robustness of the inversion.
