  1. General
    1. Due to SBS, Compton racks will move to place unknown.
      1. Need to document everything so that it can be reestablished
  2. Laser
    1. Online results show consistent results for the alternate polarization state.
  3. Photon Detector
    1. Spectrum
      1. Managed to get a measurable offset in the spectrum.
      2. When we project the BPMs to the collimator, then y=0mm is not the centre. It looks like y=+1mm is the centre.
      3. We need a summary of all the pointing spectrum runs.
    2. Linearity
      1. Variable LED appears to have broken. Couldn't be repaired in the time available.
      2. More linearity runs needed to give equivalent load to the CREX running conditions.
  4. Analysis
    1. Begin offline analysis with a respin, particularly of early data with improved cycle detection.
