Plan for 4/13 and 4/14 FPP commissioning.
  1. Beam tuning and Moeller for 3.335 GeV beam. 20 hours

  2. Do alignment of chambers . About an hour of data.

  3. Do measurement at Q2 = 0.8 to measure helicity of beam to 3% or h = 0.4 +- 0.012 . At the same time remeasure (Ge/Gm to 4% . Measurement will take 6 hours. Assume 50% uptime for 12 hours total.

  4. Do measurements at +-3% delta to measure the false asymmetries in different parts of the focal plane. To get error of 0.001 need 2.5 hours. 1/2 hour for magnet changes. Assuming 50% uptime then 11 hours total.
