Notes
- This event was included in Catalog 1.
- 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 the commissioning period (before 4 September 2018) when system performance and sensitivity were uncharacterized and thus should be excluded from population studies.
