  1. EFW SOC DATA John Wygant SWG June 18-19. 2009 Redondo Beach

  2. 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

  3. 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)
