- T100, T90, and T50 are lower limits. The burst came into field of view at ~T0-200 s.
- The event data are only available for part of the burst duration.
- Spectral analysis is only available for part of the burst duration. 

- The first peak at ~ T0-190s occured during a pre-planned slew so did not triggered BAT. The event data on HEASARC does not cover the first peak, thus we use the data from the original analysis at /local/data/bat1/prebascript/trigger537195/batgroup_hand_proc/00537195000/bat/event (likely from the pass data or the SDC data).
