: magnetic field: Broadband electrostatic noise (BEN), Electron cyclotron harmonic
wave (ECH), mercury kilometric radiation (MKR), magnetic noise burst (MNB) and
Mercury continuum radiation (MCR).
Voltage measurements from the electric antennas are processed first into
spectral data by a wavelet-like method and then the plasma temperatures
and densities are deduced by fitting a quasi-thermal noise spectrum model.
SORBET is based on an heritage of the HF receiver of the RPWS exper-
iment onboard Cassini, from which the quasi-thermal noise spectroscopy
is now providing electron temperature and density in the inner magneto-
sphere of Saturn.
