SOHO EPHIN corrected electron dataset
Description
Each file provides corrected data for the SOHO EPHIN electron channels, as follows:
| file name | channel | effectiv energy | start date | end date |
| E150_1997_2025 | E150 | 0.387 MeV | 1997-01-01 | 2024-12-31 |
| E300_1997_2017 | E300 FME | 1.080 MeV | 1997-01-01 | 2017-10-03 |
| E1300_1997_2017 | E1300 FME | 3.854 MeV | 1997-02-17 | 2017-10-03 |
| E1300_2017_2025 | E1300 FMDE | 1.147 MeV | 2017-10-05 | 2025-02-12 |
FME stands for Failure Mode E and FMDE for Failure Mode D E. In 2017 during the switch from FME to FMDE the former E300 FME and E1300 FME were combined to the E1300 FMDE.
The files contain the following columns:
- Date Time: Date and Time with the format yyy-mm-dd hh:mm:ss.sss
- The electron channel E150, E300 or E1300: electron flux in (cm^2 s sr MeV)^-1
- err_max: estimation of the max error of the electron flux in (cm^2 s sr MeV)^-1
- err_min: estimation of the minimum error of the electron flux in (cm^2 s sr MeV)^-1
- flag: SOHO EPHIN status flag
- corr: Correction factor used in the calculation with the uncorrected count rates
