Preserving Reflection Amplitudes During Partial Stacking in Inhomogeneous Media - Azimuth Moveout Versus Dip Moveout

Dip moveout (DMO) is often applied to prestack data to better preserve dipping events when performing partial stacks over ranges of offset. Optimally preserving amplitudes during the partial-stacking process is important for structural imaging, but it is crucial for reservoir-attributes analyses such as AVO and impedance inversion.
