 * Plot A-scans using the Python module ``plot_Ascan.py``. The module uses matplotlib to plot the time history for the electric and magnetic field components for all receivers in a model (each receiver gets a separate figure window). Usage (from the top-level gprMax directory) is: ``python -m tools.plot_Ascan my_outputfile.out``.
