This data set contains Van Allen Probe A 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/(ssrcm^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. Level 3 data include all level 2 data plus spacecraft positions, pitch angles of the six telecopses, and derived magnetic field values. The processing is done in a series of algorithmic steps in which the EMFISIS (Electric and Magnetic Field Instrument Suite and Integrated Science) magnetic field data is loaded, the ECT (Energetic Particle, Composition and Thermal Plasma Suite) magnetic ephemeris data is loaded, the Level 2 intensity data file is copied, and the pitch angles are calculated and placed into the copied Level 2 file, creating a Level 3 file.

Ephemeris Time of the start of the accumulation for this measurement.
UTC
SCLOCK_Full
The ephemeris time at the start of the measurement.
The ephemeris time at the mid-point of the measurement. For multi-spin measurements the midET is centered so that it properly represents the time to be used to calculate the look direction of the instrument.
The ephemeris time at the end of the accumulation of the measurement
Identifies the telescope used to collect the measurement
Identifies the channel used to collect the measurement
Midpoint energy of the measurement channel. A value of -1 indicates that an energy definition for this channel is not applicable
