Interpolation within ray tubes - state of the art

Petr Bulant


Ray tracing followed by calculation of travel times and other quantities at specified points by means of interpolation within ray tubes is a method which was developed in the SW3D consortium several years ago. The emphasis was put on calculation of all existing ray--theory arrivals, and not the first arrivals only. The method was successfully applied by the SW3D researchers in many applications. The method was also described in several papers published in previous reports of the consortium and also in reviewed journals.

As the method appears recently to be of higher interest of at least some consortium members, we present here this paper, which aims to present a short description of the method, to briefly mention its numerical realization and the computer codes developed for the method, to give an overview of the recent applicability of the computer codes, to shortly mention the plans for future extension of the method, and to present the list of examples of the application of the method.
