List of currently available key parameters for Interball Auroral Probe.

  1. Orbital data : INTERBALL AZ GSE and GSM cartesian coordinates, GSE cartesian velocity (once per 10 minutes).
  2. Interball  AZ probe energetic particle data (2 min): Electron fluxes in 26-29 and 25-28 keV energy ranges and proton fluxes in 18-24 and 20-26 keV from DOK-2 experiment. Status flags of DOK-2 experiment included.
  3. Magnetic field data from IMAP experiment. Magnetic fileld absolute value and magnetic field index (the difference between absolute value and model value), status flag.
  4. Measurements of spectra and anisotropy of electrons witin energy ranges 20-45 keV from two time-of-flight detectors EM-1-1 and EM-1-2 from SKA-3 experiment.
  5. Ion Composition (PROMICS).  Counts of H+ and O+ ions are accumulated during one spin period by detectors D6 (antisunward looking), D8 (spin plane), D10 (sunward looking) of TRICS2 subsystem (1.0-30 keV).
  6. Low energy ions dynamics in the polar ionosphere and magnetosphere (HYPERBOLOID). Ion composition and 3-D distribut functions,    M = 1-32 (with H+, He, O++, O+ routinely), 0.1 < E < 80.  Hyperboloid  key  parameter  plots are only intended for qualitative event identification.  For  further  information,  high  temporal  resolution data, and distribution functions, please email to (PI,CETP/CNRS, France) or (co-PI, IKI, Russia).
