Selection criteria for flux and power data: |V|>0.2, SNR(X)>10dB and SNR(Z)>10dB Tabulated flux and power data = 0.00e+00 correspond to absence of detected flux under the above selection criteria. Tabulated flux and power data = -1.00e+00 correspond to data gaps. For more details, see Appendix of paper: L. Lamy et al., J. Geophys. Res.,113, A07201, 2008.
