Differences in the SEPMOD modelled peak intensities of the 2021 October 9 SEP event at the various observers using the default code and the two fixed-source options.
| Observed | Default | + Solar flare | + Coronal shock | |
|---|---|---|---|---|
| Bepi | 2.232 | 19.123 (857%) | 32.308 (1447%) | 21.487 (963%) |
| SolO | 1.734 | 0.245 (14%) | 0.371 (21%) | 1.069 (62%) |
| PSP | 1.963 | 0.116 (6%) | 4.159 (212%) | 1.202 (61%) |
| STEREO-A | 1.471 | 0.081 (6%) | 0.289 (20%) | 0.862 (59%) |
| Earth | 0.047 | 0.184 (391%) | 0.184 (391%) | 0.411 (874%) |
Notes. The reported fluxes refer to the orange SEP time series in Figures 6–8, with energy ranges of 5.9–9.1 MeV at Bepi, 14.6–15.7 MeV at SolO, 13.5–16.0 MeV at PSP, 15.0–17.1 MeV at STEREO-A, and 7.8–25 MeV at SOHO. The units are [cm2·sr·s·MeV]−2 for all reported values. The percentages in parentheses for the SEPMOD runs are calculated with respect to the corresponding observed fluxes.
