COSPIN/HFT 0.28-7.0 MeV Proton Spin-Averaged Flux based on counting rate F1J(0)

Column_6

Nominal 10-minute average HFT spin-averaged flux based on counting rate F1J(0) responding primarily to 0.7-0.9 MeV protons. This flux represents one step in a 16 step sequence of discriminator levels. The step is identified in the rate name, where J(x) implies step x. In the most common operational mode the discriminator level advances one step with each readout of F1 (16 s at 1024 bps). Each complete cycle thus takes 256 s (at 1024 bps).

Since the energy range is defined entirely by a discriminator level on the single 18 micron thick Silicon detector, other high energy nuclei with energy losses in the detector greater than that of a normally incident 0.28 MeV proton will also contribute to this flux. The total accumulation interval for this rate is much less than the 10 minute nominal interval since it represents one step in a 16-step sequence of discriminator levels.

COSPIN/HFT Proton 32-Sectored Flux based on counting rate F2S

Columns 27 through 58

Nominal 10-minute average HFT spin-averaged fluxes based on counting rate F2s, which split directionality of the F2 fluxes using 32 spin sectors. The counting rate responds primarily to protons in the energy ranges 0.29-6.7 MeV or 0.55-1.95 MeV, depending on whether the F2 threshold is set low or high respectively. The state of the F2 threshold is low if column 23 contains fill, and high if column 22 contains fill. See Anglin et al., J. Geophys. Res., 102, 1, 1997 for more detailed discussion of using the HFT F2S sectored rate.

Since the energy range is defined entirely by a discriminator level on the single 18 micron thick Silicon detector, other high energy nuclei with energy losses in the detector greater than that of a normally incident 0.29 or 0.55 MeV proton (depending on the state of the F2 discriminator) will also contribute to these fluxes. Since the total accumulation time in each sector is less than 20 s in the nominal 10 minute averaging period, statistical accuracy of these sectored fluxes in a single averaging interval is usually poor except in large flux enhancements, most commonly produced by large solar energetic particle events, but also by the high radiation levels in the magnetosphere of Jupiter.
