Appendix C: Graphs Showing Follow-up Measurements

This section provides graphs of the emission data from the SF GPR antennas and contrasts them to the background ambient emissions from the rural environment and to the maximum emissions criteria. In cases where there was emissions notching, the notch frequencies are provided on the bottom axis of the graphs.
