This Level-3 data set contains Van Allen Probe B RBSPICE (Radiation Belt Storm Probes Ion Composition Experiment) TOF x energy proton rates that are measured at high-energy and low-time resolution 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. 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 value using the SM reference frame, and position of the spacecraft in SM coordinates. Level 3 data include the pitch angles of the six telescopes, based upon the measured magnetic field received from the EMFISIS (Electric and Magnetic Field Instrument Suite and Integrated Science) instrument. This processing is done in a series of algorithmic steps in which the EMFISIS magnetic field data is loaded, the ECT 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.
The time of the start of the measurement in as a UTC time string (CCYY-DOYTHH:MM:SS.hhh)
The time at the start of the measurement of the Spacecraft Clock as (#/Ticks:Fine)
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
FPDU: Proton flux spectrograms in energy, by telescope in sector order
Telescope-energy images
The percentage error of the measurement.
RMS Error of the natural log of the flux for each channel.
Quality flag for the measurement for each telescope/channel/timestep. .see PREBM standards for definition
