EFW SOC DATA John Wygant SWG June Redondo Beach

Draft EFW provided science quantities The EFW team will provide and display the following data in support of SOC activities: 2-D Spin fit electric field measurements (6 second resolution) with a preliminary VxB subtraction Spacecraft potential as indicator of density: (V1+V2)/2 (32 samples/s ) Instantaneous spin plane electric field vectors (32 samples/s) Fast Broadband E-field peak/average filter data (8 samples/s; 8-16 frequency bins over 1Hz -2kHz) Begin and end times, sampling rates, sampled quantities of bursts data stored in instrument memory, other information on instrument mode Frequency vs time spectra of E and B (as calculated on board). Detrended spin axis E-field component 32 samples/s EFW will have a variety of measurements that are used for diagnostic purposes ie V1s, V2s, V3s, V4s, V5s, V6s

Desired science quantities from other instruments/platforms The EFW team “desires” the following data from other instruments Indicator of plasma density from HOPE HOPE; ECT;REPT; RBSPICE ion/electron energy time spectrograms and or line plots vs time (or L-value) from representative energy and pitch angles to indicate intervals of injection and perpendicular or parallel acceleration (similar to CDAW WEB). 3/decade. Could data include in orbit vs L value format; Electrons: 100 eV to 6 MeV; PA at 30 degree intervals H+,O+: 100 eV to 400 keV (counts/s?differential energy flux?).PA at 30 degree PA. EMFISIS: Magnetic field vector in inertial coordinate system (DSC, GSE) (16Hz) model subtraction EMFISIS: Frequency time spectograms including information on power up to 400 kHz). power of different waves; plasma line, hiss, chorus, AKR Information on begin times and durations and nature of high time resolution modes SC attitude and position information Ability to detrend fluxes; ability to subtract average flux/counts from previous orbit to provide information on changes from orbit to orbit: Information from from Millstone Hill (John Foster is an EFW Co-I) Geomagnetic activity indices (AE,DST) IMF information…(velocity density, magnetic field) Information on BARREL status, position of payloads, preliminary information on X ray counts Information from other relevant spacecraft (position, data?- SSC)
