- T100, T90, and T50 are lower limits. Looks like the burst occurs during SAA (so there was no data at the beginning of the burst). Also, the burst seems to have another pulse at around T0+500 s to T0+600 s, the burst went out of the field of view afterwards. 
- The event data are only available for part of the burst duration.
- Spectral analysis is only available for part of the burst duration.

- To double check that this late time emission is not due to incomplete substraction of noisy background, we created an image from T0+500 to T0+550, this burst is detected at SNR = 5.9. (see script at /local/data/bat1/alien/Swift_3rdBATcatalog/event/batevent_reproc/trigger533060/special_script)
