BAT: This burst occurred during the period of recovering the thermal control system (Barthelmy et al., GCN Circ. 18562). The CZT bias voltage has been reduced to -150v (instead of the normal -200v) and as such the energy scale is not fully calibrated. Therefore, an accurate spectral analysis is unavailable.

* The data were put in a different sequence not labeled with the trigger number but the trigger number is correct.

NOTES:

  1. Table does not contain about ~10 weak detections which we did not distribute because we were uncertain about their validity.
  2. All numbers are preliminary and may be revised as we do reprocessing (s/w improvements, thinking/experience improvements).
