Anisotropic migration velocity analysis of synthetic data from RMO transformation in anisotropic ADCIGs

In the preceding section, we derived the expression of the RMO in anisotropic ADCIGs as a function of anisotropic parameter perturbations and demonstrated its accuracy for different types of velocity model perturbations. In this section, we perform anisotropic MVA on the same synthetic data and analyze the accuracy and convergence of our estimation method. We also illustrate caveats in the computation of anisotropic velocity spectra and demonstrate that as few approximations as possible should be made in order to attain accurate anisotropic parameter estimates.
