Paul King has this outline for a new scheme to readout the delayed helicity for Physics Events Trigger (instead of using Scalers RingBuffer):
Running in background:
- On Pattern Start
- Increment pattern counter
- Grab Reported Helicity
- Push onto running seed (30-bit)
- Clear pattern phase counter
- On T_Settle Transition
- Increment pattern phase counter
- Increment T_Settle counter
Then, when a physics event triggers DAQ:
- On CODA Event
- Report current seed value
- report current pattern phase
- Report current pattern and T_Settle counter
