List of observed photon beam coherent peak shifts to take a look at

• March 30 2018 - before and after the repositioning of the diamond.
• before March 30, last run before the beam went down and first run after it came back, unless Hovanes realigned
• https://logbooks.jlab.org/entry/3761564 - look at difference between reference and observed peak
• CPP - several instances of wild beam energy shifts reported NB nominal position was around 6 GeV not 9 GeV
• Demon's plots show a variety of interesting coherent peak positions near the start of 2017
• logbook entry Christiano nudged 6-25-22 00:39 run 100667
