Description
ASCII Data File containing all Ulysses COSPIN/HET Daily Average PHA based Flux Data. Each Day is represented by one Line containing, in eleven Columns:
Fractional Year since 1900 of Midpoint of Average (Day 170, 2007 = 107.46438), Fractional Day of Year of Midpoint of Average (January 1 = 1, so Day 170 = 170.5), Flux of 39-70 MeV Protons, Statistical Error on Flux of 39-70 MeV Protons, Flux of 71-94 MeV Protons, Statistical Error on Flux of 71-94 MeV Protons, Flux of 39-71 MeV/n Helium, Statistical Error on Flux of 39-71 MeV/n, Helium Flux of 71-94 MeV/n Helium, Statistical Error on Flux of 72-95 MeV/n Helium, and Seconds of Data Coverage during the Day, Invalid or Missing Data are represented by -1.000E+00

COSPIN/HET 39-70 MeV (H4) Proton Flux
ParameterKey
Column_3
Description
Flux [1/(s cm^2 sr MeV)] of 39-70 MeV protons averaged over one Day.
Caveats
Energy ranges are approximate, based on a minimum error analysis as a function of spectral form (so-called Bow Tie analysis). The effective geometric factor and end point energies have been chosen to give minimal dispersion in calculated fluxes over a range of plausible proton spectra using events generated from various spectra by Monte-Carlo simulations. Typical systematic uncertainties resulting from such spectral dependence of the response are of order +/- 10 per cent on the flux, in addition to statistical counting uncertainties.
