  1. General/CREX analysis
    1. Beam through the chicane. Looked good.
    2. There were laser-on drifts due to beam motion in the chicane.
    3. Ops want us to use the Moller lock during production. This would require changing the lock. We're happy with any solution that locks to the Compton table BPMs.
    4. Some snail have very good data: good separation, small error, good chi2. Some have double peaking in the pedestal.
    5. Use snapshot pedestal to correct accumulators? Code doesn't exist, would need to be developed.
    6. TODO Make plot of pedestal as function of time from snapshots.
    7. Discussion about reading out tube voltage and current or DAQ temperature.
