2.3.2 spase://NASA/NumericalData/RBSP/B/RBSPICE/L3/ESRLEHT Van Allen Probe B RBSPICE Low Energy Resolution Electron Rates converted Level-3 data 2021-04-27T15:38:11Z 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. 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.

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. ns Other UTC UTC UTC Other SCLOCK_Full SCLOCK_Full SCLOCK_Full Other ET ET The ephemeris time at the start of the measurement. seconds Other MidET MidET The ephemeris time at the mid-point of the measurement.
