2.2.2 spase://VWO/NumericalData/POLAR/PWI/LHFWR.2kHz.PT0.0000224S Polar Plasma Wave Instrument, High Frequency Waveform Receiver, 2 kHz, Time Domain Fields 2012-06-22T00:00:00Z An FFT on 2048 values was used in calibrating the data; i.e., perform FFT, calibrate in frequency domain, perform inverse FFT to get calibrated time series. Data are lowpass filtered so that the data are valid only up to 2 kHz. The three orthogonal magnetic field components are given in units of nT/Sec rather than nT because the response of the searchcoils across the passband is not flat. In order to obtain units of nT, the data would need to be digitally filtered to the frequency of interest and then integrated over time. Integrating over the entire passband could possibly destroy the resolution of the higher frequency components since the low frequency noise, if present, will dominate. Effective Bandwidth is 1.5*delta_f, where delta_f depends on the size of the FFT used to convert to the frequency domain, and delta_t. The unattenuated frequency range for this file type is 20Hz to 2000Hz. U. Iowa, Donald. A.
