TL;DR: In this paper, the authors reported the unsaturated gamma-ray profile for the first 600 ms of the SGR 1806-20 massive flare, with a time resolution of 5.48 ms, indicating either that the energy release mechanism was extremely efficient or that the interior magnetic field is much stronger than the external dipole field.

TL;DR: The Magnetic Field Experiment (MGF) as mentioned in this paper was built for the Arase (ERG) spacecraft mission to investigate particle acceleration processes in the inner magnetosphere, where the magnetometer switches the dynamic range between ±8000 and ± 60,000 nT, depending on the local magnetic field intensity.
