RSTTI Package: Ray Based Seismic Travel Time Inversion
MetadataShow full item record
This report describes improvements of an existing package (RAYINVR) [Zelt and Smith, 1992]. The RAYINVR package performs 2-D ray tracing and iterative damped least squared travel time inversion. This report briefly reviews the RAYINVR package, presents the RSTTI package, illustrates each tool of the RSTTI package with synthetic or real data examples.
