- pyrfu.mms.eis_proton_correction.eis_proton_correction(flux_eis)[source]#
Corrects proton flux values based on FPI/HPCA/EPD-EIS cross calibration. Correction to the EIS PHxTOF data are made by applying an energy-dependent numerical correction of the form:
where E is energy and \(\alpha_{PH} = -0.3\) , \(\beta_{PH} = 0.049\) , \(\gamma_{PH} = 0.001\) are coefficients. Minor adjustments were also made to the lowest energy EIS ExTOF data to correct for foil efficiencies. This correction is of the form:
where E is energy and \(\alpha_{E} = -0.3\) , \(\beta_{E} = 0.049\) , \(\gamma_{E} = 0.001\) are coefficients.
