REFRACTOR

REFRACTOR provides the intercept time method, delay time method, ABC method, and generalized reciprocal method (GRM) for seismic refraction surveys. You can automatically or manually pick first breaks, easily assign first arrivals to layers, and quickly phantom time-distance curves. The velocity and elevation may vary along a profile and there are no limits on the number of layers
