Conclusions

We construct 2D and 3D sensitivity kernels for wave-equation MVA and study their dependence with respect to the data source, the frequency content, and the type of image perturbation. Sensitivity kernels illustrate the complications of wave propagation in the cases of rough salt bodies and the frequency-dependent illumination subsalt. With this type of analysis, we also illustrate some of the reasons why traveltime tomography is less than ideal for subsalt velocity analysis.
