Parker Solar Probe, FIELDS Radio Frequency Spectrometer, RFS, Low Frequency Receiver, LFR, Spectra, Level 2 (L2), 7 s and 56 s Data

The exact frequency bins are selectable and are included as metadata variables in this file. The Level 2 data products contained in this data file have been calibrated for the preamp and RFS analog section response, the Polyphase Filter Bank, PFB, and the Fast Fourier Transform, FFT, spectral processing as described in reference [3]. Corrections for base capacitance and antenna effective length have not been applied.

These corrections will be applied in Level 3 RFS data. Therefore, the units for all spectral quantities are given in V^2/Hz. The time resolution of the RFS data vary with instrument mode.

During encounter, which is when PSP is within 0.25 astronomical units, AU, of the Sun, the cadence for RFS HFR and LFR spectra is typically about 7 s. During cruise mode, which is the default mode for operations outside of 0.25 AU, the cadence for HFR and LFR spectra is about 56 s. References:
