We show in Appendix A (equations (41) and (45))
Using equations (23), (24) and (25), the relationship of the imaging depth in the angle domain with respect to perturbations in the anisotropic parameters can eventually be written as follows:
This is the fundamental equation of this section, extending the equation given in Biondi (2005a) to include dipping reflectors.
The residual moveout is defined as the difference between the reflector movement at finite aperture angle and the reflector movement at normal incidence. The latter is given by
