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 affected by miscellaneous system problems (e.g. data corruption or timing errors) and should be excluded from population studies.
