Translations:Alternate approaches to phase rotation/2/en

Wavelet processing produces a seismic section, but the wavelets on the section are not quite symmetric wavelets, as desired. The practice is to rotate each trace on the processed section by a fixed amount to yield (approximately) symmetric wavelets. To this end, a visual or analytic means is used determine the optimum value of the constant-phase rotation that should be applied to each trace in the seismic section.
