- Only part of the event data are used in order to have a more reasonable estimation of burst durations. Due to noisy background, only use event data with T < T0+700 to get better burst duration and higher signal-to-noise ratio of the refined position.
- T100, T90, and T50 might be lower limits. There might be additional burst emission after the end of T100, but it is hard to tell due to the poor statistics as the burst move toward the edge of the field of view (GCN 6933).
- Refined position calculated with time interval and energy band determined by the flight software (T0 to T0+376 s; 15-50 keV).
