Agenda

  • Proposed Oct 3 meeting: 12-4pm


  • Notes on remaining analysis
    1. Acceptance function
      • optics model - still problems in theta reconstruction. (Siyu, Nilanga)
      • pointing: complete the precision estimate, cross-checks (Siyu, Nilanga)
      • sim. focal plane variables (Hanjie, Devi)
        • scan of focal plane acceptance: contributor to syst uncertainty? (Ryan, Hanjie)
      • apparent vs vertex: radiative correction. Model variations? (Ryan)
      • variation in data (various Q2 runs) (???)
      • selecting “nominal” kinematics, formulating correction factor (Kent with all)
    2. Asymmetry analysis
      • Adding modulation data back in (Tao)
      • filter for end-of-target-life runs (Tao)
      • settling on a systematic error (Tao)
      • crosschecks (Weibin)
      • summary plots (Tao, Weibin)
    3. Backgrounds
      • rescattering (done)
      • poletip (may be a later study?)
      • Carbon background
        • run time per targets
        • measured target thickness (and uncertainty)
        • simulate carbon acceptance with lead radiative tail
        • (cross-check rate (width) estimates between thick 12C and Pb sandwich targets)
    4. Compton
      • complete compilation/filtering (with latest cuts on signal instabiity) (Adam)
