Table 1
Criteria used to define the solar flare and coronal shock SEP sources.
| Solar flare source | Coronal shock source | |
|---|---|---|
| Spatial location | AR open field at 2.5 R⊙ | Maximum CME width at ∼10–15 R⊙ |
| Injection time | X-ray flare peak | Type II onset |
| Energy spectrum | Steep/soft power law | Rollover spectrum |
| Maximum intensity | Scaled with flare class | Scaled with CME speed |
| Temporal profile | Exponential decay from flare time | Exponential decay from Type Il time |
| Decay constant | Scaled by flare magnitude | Based on CME transit time to 21.5 R⊙ |
