Notes
- The pulse emission region was extended during fluence estimation.
- Flux and fluence. Flux/fluence estimate has an unacceptably large fractional uncertainty.
- Fitburst. Signal above 620 MHz artificially zeroed by incorrect calibration gains. Spectral parameters not representative of FRB's true broadband spectrum.
