Abstract
The complete set of CRS parameters can be extracted<br>from seismic data by an application of modern local-slopeextraction<br>techniques. The necessary information about<br>the CRS parameters is contained in the slopes of the<br>common-midpoint and common-offset sections at the central<br>point. As demonstrated by a synthetic data example,<br>the slope extraction is sufficiently robust to allow for derivation<br>of the extracted slope field. This enables the calculation<br>of the CRS parameters from the extracted slopes and<br>their derivatives. In this way, the CRS parameter extraction<br>can be sped up by several orders of magnitude.
