The MATLAB code for equivalent offset migration has been updated to include the processing of converted wave data. This new procedure estimates a converted wave velocity that is then used to estimate a shear wave velocity. The compressional and shear velocities are then used in the double-square-root equation to compute traveltimes.
Parameter options are defined. Some of the new parameters define a limited offset and spatial range during the gathering process to form converted wave gathers with one converted-wave velocity.
