These data are derived from power spectra (10.5 kHz to 1.7 MHz) acquired by the low-frequency receiver (LFR) of the Radio Frequency Spectrometer (RFS), part of the FIELDS instrument suite on PSP.
The technique of QTN spectroscopy consists of using the power spectrum of the voltage induced on an electric antenna by the particle quasi-thermal motion, measured by a radio receiver connected to an electric antenna. The signature of the electrons is a line at the electron plasma frequency, which leads to the total electron density (proportionnal to the square of electron plasma frequency), whereas the shape of the line reveals the electron kinetic temperature, as well as its themral (core) and suprathermal components.
