The solo_L3_mag-rpw-scm-merged-256 data product is generated from solo_L3_multi-mag-rpw-scm-merged-rtn-256 to display the magnetic field spectra evolution below 128 Hz of the 3 components in the RTN frame.
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.
On each spectrogram, the magnetic field curve is superimposed with its own scale on the right.
