High Energy Helium fluxes obtained with SOHO-EPHIN

mission_long_monthly_quiet.csv and mission_long_daily.csv contain Helium spectra for four energy channels for the time from 1996 to October 2017. The monthly header is as follows: Year Month 57MeV/nuc 57MeV/nuc_stat_err_rel 57MeV/nuc_sys_err_rel 65MeV/nuc 65MeV/nuc_stat_err_rel 65MeV/nuc_sys_err_rel 78MeV/nuc 78MeV/nuc_stat_err_rel 78MeV/nuc_sys_err_rel 95MeV/nuc 95MeV/nuc_stat_err_rel 95MeV/nuc_sys_err_rel Each energy contains a flux in (m^2 sr s GeV/nuc)^-1 (xMeV/nuc), a relative statistical error (xMeV/nuc_stat_err_rel) and a relative systematic error (xMeV/nuc_sys_err_rel). The daily header is as follows: Year Month Day 57MeV/nuc 57MeV/nuc_stat_err_rel 57MeV/nuc_sys_err_rel 57MeV/nuc_n_particles 65MeV/nuc 65MeV/nuc_stat_err_rel 65MeV/nuc_sys_err_rel 65MeV/nuc_n_particles 78MeV/nuc 78MeV/nuc_stat_err_rel 78MeV/nuc_sys_err_rel 78MeV/nuc_n_particles 95MeV/nuc 95MeV/nuc_stat_err_rel 95MeV/nuc_sys_err_rel 95MeV/nuc_n_particlesEach energy contains a flux in (m^2 sr s GeV/nuc)^-1 (xMeV/nuc), a relative statistical error (xMeV/nuc_stat_err_rel), a relative systematic error (xMeV/nuc_sys_err_rel) and the number of particles used to calculate the flux (xMeV/nuc_n_particles).The simulation files helium_ephin_backward_200_8000_2mrd.sim (particles simulated to hit EPHIN through the SOHO spacecraft) and helium_ephin_forward_200_8000_2mrd.sim (particles simulated to hit EPHIN through the nominal opening) contain the simulations used to obtain response functions for the fluxes.Their header is as follows: det1 det2 det3 det4 det5 det6 anti det1seg det2seg eventid E0 detx denotes the energy loss of the particle in detector x, anti denotes the energy loss in the anticoincidence, detxseg denotes the segment in detector x the particle hit, eventid is the simulation id, and E0 is the primary energy of the particle in MeV. 2*10^9 particles were simulated from the nominal direction and spacecraft direction each (4*10^9 overall particles). The simulated energy spectra follows a power law spectrum with gamma=-1.
