THEMIS-D: Fluxgate Magnetometer Measurements 1/128s

ResourceID
spase://DLR/NumericalData/THEMIS/D/FGM/PT0.0078125S

Description
Spacecraft-collected fluxgate magnetometer measurements: Decimated TeleMetry High, DSL, GSE and GSM coordinates, cadence 3s-1/128s. The high-resolution data is available only for time intervals when the instrument was switched into a high-resolution mode. Sensor and electronics design provided by TUBS (Glassmeier, Auster) and IWF (Baumjohann, Magnes)
