* The data were put in a different sequence not labeled with the trigger number but the trigger number is correct.
NOTES:
- Table does not contain about ~10 weak detections which we did not distribute because we were uncertain about their validity.
- All numbers are preliminary and may be revised as we do reprocessing (s/w improvements, thinking/experience improvements).
