THEMIS-D: Electric Field Instrument, EFI, Electric Field Measurements. The L2 Product is a 3D Estimate of the perpnedicular Electric Field, Eperp, derived from the Spin Plane E-Field Measurements assuming E ⋅ B = 0, using relevant Flux-Gate Magnetometer, FGM, Data. This Data Product includes Spin-Averaged, and Fast Survey Field Data. The Spin-Averaged Data, EFS_DOT0, has approximately 3 s Time Resolution. Fast Survey, EFF_DOT0, Data has 0.125 s Time Resolution.
