This Level 2 product is a 3D estimate of E_perp 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. NASA contract NAS5-02099 and V. Angelopoulos for use of data from the THEMIS Mission. Specifically: J. W. Bonnell and F. S. Mozer for use of EFI data. spase://SMWG/Person/Vassilis.Angelopoulos PrincipalInvestigator spase://SMWG/Person/John.W.Bonnell CoInvestigator spase://SMWG/Person/Forrest.S.Mozer CoInvestigator THEMIS Home Page http://themis.ssl.berkeley.edu/index.shtml The THEMIS project home page.

The spin plane booms for THEMIS A were not deployed until January 14, 2008 at 1700 UT, any EFI measurements before this date should not be used. See THEMIS website for more information.
