BDFFT: software for finite-frequency traveltime tomography

BDFFT contains a set of fortran and c-shell written programs used to conduct (multiscale) finite-frequency traveltime tomography beneath the region of interest using cross-correlation measured P or S traveltime residuals from teleseismic earthquakes.

Installation and tutorials are described in readme_BDFFT.
