Which set of data would you like to see info about:
THEMIS Level 2 EFI file info:
Electric Field Instrument (EFI) Electric field measurements. The L2 product is a 3D estimate of Eperp derived from the spin plane E-field measurements assuming E dot B = 0, using relevant FGM (Flux-Gate Magnetometer) data. Includes spin-averaged and Fast-survey field data. Spin-averaged (EFS_DOT0) data has approximately 3 second time resolution. Fast-survey (EFF_DOT0) data has 1/8 second time resolution.
