SOHO Comprehensive Suprathermal and Energetic Particle Analyzer (COSTEP) Electron Proton Helium Instrument (EPHIN) Intensity Level 3 30-minute Data in CDF Format

2023-10-01 00:00:00Z

The data include 30-minute proton and He fluxes in 4 energy ranges (4.3-7.8, 7.8-25, 25-40.9, 40.9-53 MeV) and their systematic and statistical uncertainties. Also included EPHIN status flag and measurement accumulation time. This CDF dataset was converted from the original ASCII dataset at the SOHO Archive https://soho.nascom.nasa.gov/data/archive.html. Documentation of the original ASCII COSTEP-EPHIN Level 3 dataset, including energy ranges of Level 3 channels and status flag description (see Section 5), is available at http://ulysses.physik.uni-kiel.de/costep/level3/l3i/DOCUMENTATION-COSTEP-EPHIN-L3-20220201.pdf. Description of the COSTEP-EPHIN instrument and scientific scope can be found on the COSTEP home page http://www2.physik.uni-kiel.de/et/ag-heber/costep/ and on the SOHO mission home page https://sohowww.nascom.nasa.gov/.
