This data set contains ARCAD-3 Isoprobe plots of waveform (tracking frequency of the extremum). The high resolution data correspond to a frequency tracking of the resonance or an anti-resonance of the mutual impedance response. As the resonance frequency is related to the electron density and the anti-resonance frequency to the Debye length, these data (used as waveform data) allow studies of density and/or temperature fluctuations. The extremum trackings, one per probe, are available in the...
