available for public use; though the authors stress that use of non-gain matched data may lead to artifacts in the transition between the MAG and SCM sensor ranges.

![Gain difference between SCM and MAG measured over their shared observations range ($x$, $y$, $z$ axes shown in black, blue, red). The measured distribution of gain differences is plotted as a set of points. The mean at each frequency is plotted as a sold line, while the median gain difference in each axis from 3-10 Hz is plotted as a dashed line. The average gain difference is roughly constant over this range. The feature at 7 Hz corresponds to a reaction wheel (which has a lower signal in the SCM due to the relative positioning of the sensors).[]{data-label="gain_error"}](fig8)

A quantitative determination of the accuracy of the timing between the MAG and SCM data is performed by computing the short time Fourier transform cross-spectra of each of the three combinations of signals. The short time cross spectra is defined as $$S_{12}=\langle\mathcal{F}\{B_1(t)\}\mathcal{F}^{\dagger}\{B_2(t)\}\rangle$$
