Acoustic wavefield evolution as function of source location perturbation

Examples

I test the developed partial differential equations on two examples: a simple lens velocity model and the complex Marmousi model. In both cases, I compare the wavefields obtained from a direct finite difference solution of the wave equation for a particular source to that obtained by perturbing the solution from a nearby source using the first and second order approximations. In the Marmousi case, I also compare the resulting surface recorded synthetic data for all options.
