Notes
- This event was detected in the sidelobes of the CHIME primary beam.
- This event should be excluded from parameter inference due to non-nominal telescope operation.
- The pulse emission region was extended during fluence estimation.
- Localization. Localization not available for sidelobe events.
- Exposure. Exposure not available for sidelobe events. Event occurred on a day with low sensitivity - identified via pulsar-based monitoring of system noise - and should be excluded from population studies.
- Flux and fluence. Flux and fluence not available for sidelobe events.
