=== Outstanding rates issues ===
- Fits of Run I HI fail our method for determining MEAN and SIGMA (exponential fit fails). We took LO test runs for all of the Run I HI. We an use these to define the MEAN and SIGMA for the corresponding Run I HI targets? How to do this - flag and set those runs in the MottAnalysis script? Success will be that the Run I LO and HI data sets are no longer separated.
- Once Run I LO/HI discrepancy solved we will have Run I rates and Run II rates from analysis where the uncertainty calculation is defined here.
- To this we have additional systematic uncertainty
- Fluctuation of rates within a run (this will be the systematic over period of days e.g. stability of injector setup, slow drifts in the instrumentation), looks to be <1%
- Fluctuation of rates between runs (this will be the systematic over period of months e.g. new calibration, new beam setup), looks to be ~5%
- What else?
