solo_L3_rpw-lfr-surv-cwf-b data product is generated from solo_L2_rpw-lfr-surv-cwf-b to display the magnetic field spectra evolution below 128 Hz of the 3 components in the SRF frame. It uses both 16 Hz and 256 Hz rated samples.
The frequency scale consists of two intervals [0 Hz, 8 Hz], [8 Hz, 128 Hz], each with its own resolution.
There are two pages: the first shows the density spectrograms of the three components of the magnetic field, and the second shows the median spectrum over the period and the spectrogram of density ratios relative to the median spectrum.
