- T100, T90, and T50 are lower limits. The main pulse happens at around T0_600 s, which is after the event data range (till T0+300 s).
- The event data are only available for part of the burst duration.
- Spectral analysis is only available for part of the burst duration.
### probably need to use the survey data for this burst, like what was done in the 2nd catalog.
