  author={Anatoly I. Baumstein and John Ernest Anderson},
We describe an approach to performing wavefield extrapolation in VTI media in the case when the Thomsen anisotropy parameters δ and and vertical propagation velocity vary laterally. Our method is a combination of downward continuation with reference parameters, explicit correction filter application to account for laterally varying anisotropy, and interpolation between reference wavefields to ensure correct vertical propagation velocity. We address the questions of explicit filter design… CONTINUE READING
