This is the first official release of PyRaysum. This program generates sets of ray-theoretical seismograms for incident plane waves (teleseismic approximation) for seismic velocity models consisting of a stack of layers with planar but non-parallel (dipping) interfaces, allowing the possibility of anisotropy in the layers. Incident P and S waves are supported.
PyRaysum is a Python wrapper around the (revamped and corrected) Fortran software Raysum, originally developed by Andrew Frederiksen. A trimmed down version of the Fortran code is supplied with PyRaysum. You can find the original version here.
