Description

This data set contains Van Allen Probe A RBSPICE (Radiation Belt Storm Probes Ion Composition Experiment) TOF x (Time of Flight) pulse height hydrogen and oxygen fluxes that are measured at high-energy and low-time resolution by 6 telescopes in 28 channels from ~0.01-2.0 MeV. Data are available in physical units (counts/(ssrcm^2*MeV)) by telescope in sector order, with spin accumulations plotted at the end of accumulation. 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.

Parameter #1
Name
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.
