Solar and Heliospheric Observatory (SOHO) Comprehensive Suprathermal and Energetic Particle Analyzer (COSTEP) Electron Proton Helium Instrument (EPHIN) Level-3 Intensities 10-minute Data

Data Directory: <https://spdf.gsfc.nasa.gov/pub/data/soho/costep/ephin_l3i-10min/>

This directory contains CDF files with the COSTEP-EPHIN Level-3 intensities 10-minute data, including status flag, proton intensities with systematic and statistical uncertainties in 4 energy ranges (4.3-7.8, 7.8-25, 25-40.9, 40.9-53 MeV), and He intensities with systematic and statistical uncertainties in 4 energy ranges (4.3-7.8, 7.8-25, 25-40.9, 40.9-53 MeV/n), created from the original ASCII files at <https://soho.nascom.nasa.gov/data/archive.html>.

Description of the COSTEP-EPHIN instrument and scientific scope can be found on the COSTEP homepage <http://www.ieap.uni-kiel.de/et/ag-heber/costep/> and on the SOHO homepage <http://sohowww.nascom.nasa.gov/>. Documentation of the COSTEP-EPHIN Level3 data product, including energy ranges of Level3 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>.

Copies of the original ASCII files and a copy of DOCUMENTATION-COSTEP-EPHIN-L3-20220201.pdf are also archived at SPDF at <https://spdf.gsfc.nasa.gov/pub/data/soho/costep/ascii/>.
