dc z gz dz (4) At any point in space, the ray curvature is therefore given by the ray parameter and the local value of the sound speed gradient g(z). Ray path-length-dependent slowness model Ray path-length-dependent slowness model Xie, Zhi; Rabinowitz, Philip; Spencer, Terry 2004-09-29 00:00:00 By introducing a new parameter, slowness deviation, a ray-path-length-dependent slowness model has been previously developed. Synthetic tests indicate that for a horizontal layered slowness structure, the new model gives a good estimate of the weighted average slowness of a ray when the rays considered cover a small range of take-off angles. of an arbitrary ray is specified by the quantity p, the horizontal (radial) component of the slowness vector, which in an isotropic layer is commonly called the ray parameter. slowness parameters, which are currently used in array techniques to locate earthquakes, blasts or nuclear explosions. ... while the ray parameter deviations with respect to When the rays considered cover a … By turning the parameter server from a “system” into an “application”, this approach makes it orders of magnitude simpler to deploy parameter server applications.

The top panels show the result of doing tomography in the depth domain using and isotropic regularizer applied to the change in slowness. The radiation patterns are functions of the slowness, i.e., “ray-parameter,” and surface P-velocities and S-velocities and can be inverted for a given slowness. In order to improve the accuracy of BP imaging, a new aftershock-based correction was introduced into the BP approach to account for uncertainty of the ray parameter (slowness) caused by approximating the 3D velocity structures with a 1D reference model.
