run# 8742: delay dt=59 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
The data look like:
run# 8736: delay dt=100 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
The data look like:
run# 8737: delay dt=200 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
The data look like:
The mean of the peak is at 165.5 channel
run# 8738: delay dt=300 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
The data look like:
The mean of the peak is at 335.7 channel
run# 8739: delay dt=400 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
The data look like:
The mean of the peak is at 511.5 channel
run# 8740: delay dt=800 ns between the fall side of the common start pulse and the rise side of the fake stop signal.
