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 on a day with low sensitivity - identified via pulsar-based monitoring of system noise - and should be excluded from population studies.
