Responsibilities

- GlueX:
  - Random software problems:
    - fix disttort quiet_nan returns
    - see list
    - slow track reconstruction (and mcsmear)
      - look into speed losses due to vector sorts (jana doesn't preserve sorted order anyway), fitting
      - only track fit one PID hypothesis per charge if possible (do study to see when possible)
  - Track Reconstruction Fixes:
    - take notes on Kalman Filter
    - fitting/disentanglement of low momentum track spirals
    - track hit selection
  - BCAL Segmentation PID Study:
  - DC dE/dx Chi-squared:
  - Timing Chi-squared:
    - TOF/BCAL/FCAL Uncertainties
  - BCAL, FCAL/TOF dE/dx and Chi-squared:
  - Software Reorganization:
  - Neutron reconstruction:
- CLAS:
  - g13:
    - Reinhard study
    - ppm cross section
    - K*0 and Sigma*- cross sections
    - K0, Lambda Polarization Observables
    - acceptance studies
  - g14:
    - Online Analysis Studies
      - notify/get-approval-from curtis & reinhard, organize trip to JLab in mid-November
    - Run Coordinator
      - talk to Reinhard, figure out best time to sign up
- CLAS12/GlueX:
  - eventual k0 lambda high energy analysis (LOI, proposal, etc.)
