DSCOVR Faraday Cup (FC) Isotropic Maxwellian Parameters for Solar Wind Protons 1 minute averages

ResourceID

spase://NOAA/NumericalData/DSCOVR/PlasMag/FaradayCup/CDF/PT1M

Description

Best Fit Parameters from Nonlinear Fitting of a single, isotropic Maxwellian Velocity Distribution Function to Sets of DSCOVR Faraday Cup Measurements of the Solar Wind Thermal Proton Peak. One Minute Resolution Data are obtained by fitting to the 1 min integrated Distributions, comprising about 15 as-measured charged Current Spectra each. Reported Uncertainties are fitting Uncertainties, which do not account for so-called prior Uncertainties associated with non-Maxwellian Distributions in Nature or with Conditions that vary on Timescales faster than 1 min. The Uncertainties associated with Measurement of charged Flux as a Function of Energy are propagated. Certain Empirical Corrections have been applied.
