Notes
- This event should be excluded from parameter inference due to non-nominal telescope operation.
- The pulse emission region was extended during fluence estimation.
- Exposure. Event occurred during a period when real-time grouping/classification (L2/L3) was non-functional and should be excluded from population studies.
