- T100, T90, and T50 are lower limits. The burst duration starts earlier than MET=345107406.000000 s, when it enters the BAT FOV, and end after the end of the event data of trigger509337.
- The event data are only available for part of the burst duration.
- Spectral analysis is only available for part of the burst duration.

- This burst triggered both 509337 and 509336, but somehow the HEASARC data for both of these triggers are incomplete (and there are big gaps between data from 509336 and 509337). Therefore, the analysis uses event data from the original burst folder for the prompt analysis (/local/data/bat1/prebascript/trigger509337/batgroup_hand_proc/00509337000/bat/event; I think the data are either from the pass data or the SDC). The trigger time used is from trigger509337.
