Van Allen Probe A RBSPICE High Energy Resolution Ion Species Rates converted Level-3 Data

Ion species measured by 6 telescopes in 64 channels from ~0.05-1.0 MeV are available in physical units (counts/(s*sr*cm^2*MeV) by telescope in sector order (T0= ~110 PA, T3= ~all PAs, T5= ~70 PA). 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 calculated 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.
