Figure F5. Creation of earth model used to calculated synthetic seismograms and its representation in the resulting velocity function. Layers are hand-selected by the user to group together similar velocities. Velocities and densities assigned to layers are averages of the interpolated input velocity function. As a result, actual velocities and densities assigned to each layer are neither as high nor as low as original data points.
