Description
This data set contains Van Allen Probe B RBSPICE (Radiation Belt Storm Probes Ion Composition Experiment) low-energy resolution electron rates that are measured at high-time resolution. Unidirectional Differential Electron Flux (FEDU) measured by 6 telescopes in 14 channels from ~0.02-1.0 MeV are available in physical units (counts/(s*sr*cm^2*MeV) by telescope in sector order (T0= ~110 PA, T3= ~all PAs, T5= FEDU background). Also available are percentage error of measurement, quality flag, current sector number where each spin is dividied into 36 sectors, duration of the accumulation, current spin number of the spacecraft, orbit number, dipole L using the SM reference frame, and position of the spacecraft in SM coordinates.

Epoch
ParameterKey
Epoch
Description
Ephemeris Time of the start of the accumulation for this measurement.
Caveats
This is the Ephemeris Time saved as a TT2000 CDF Variable. The difference between the ET value and the TT value is less than a millisecond. The ET time values have an accuracy of no greater than 3 milliseconds hence it was determined that there was no reason to convert the ET values into TT.
