- check BPM: type "spot++" or "spot_L" or "spot_R" in adaq account
- Monitor bleedthrough current

- Monitor target polarization
- Check that TO is actively adjusting nmr to maximize polarization.
- Check that target is moved to 2nd cup/annealed when polarization drops too low
Replay
- Do full replay for every run (front room will only replay 20,000 events)
