Overview

The seismic data are 2D synthetic datasets generated using 2 different finite-difference forward modeling softwares in VTI media. One code was computed by Amerada Hess their code contains surface multiples, the other was computed at Stanford using SEPLIB has no surface multiples.

Data II was generated using the finite-difference modeling software developed at SEP, Stanford University. It does not contain surface multiples.
