Master CDF VAR_NOTES: 'These data are collected via the fine wire electric dipole antenna which had a tip to tip length of 215 meters.  The Ev antenna was used to collect over 99% of the E-field measurements obtained by the PWI.  Most of the time (98.3%) these data were collected via the ESA (Electric Spectrum Analyzer).  Though a small fraction of the data are from the MSA (Magnetic Spectrum Analyzer). The two analyzers have almost identical channel centers and bandwidths, except that ESA has 6 more bands above the highest band of the MSA.  When the MSA is used to read an electric antenna, the upper 6 bands are marked with fill data.  This antenna was shared with the Heppner DC electric-field experiment.
