symshot1

Simulate a seismic shot

Description

Simulate an exploration style seismic shot with ground roll, air wave, refractions and reflections.

Usage

symshot1(PLOT = FALSE)

Arguments

PLOT

logical, TRUE=plot the wiggles. DEFAULT=FALSE

Details

Arrivals are calculated based on geometric considerations with a 1D layered model.
