Stephen
-------
- meeting with Casey re. ifarm job system (swif)
  - trying to merge his work with hcswif
  - Stephen's scripts dynamically allocate disk space & memory, while hcswif
    has these hard coded
  - hcswif allows for run# ranges, as opposed to specifying each one
    individually

- updates to hcana
  - looking into putting singles trigger assignments into a PARAM file instead
    of hard coded
    - will be called HMS, SHMS instead of TRIG1, TRIG3, etc
  - adding raw untracked COINTIME variable, for untracked analysis
  - Mode-10 stuff is already included

- cleaned up UTIL_BATCH
  - divided into different run periods

Ali
---
- Analysis Plan
  - divided up Heep-COIN and Heep-SINGLES runs with Richard
  - fine tune efficiencies and offsets
  - discussed things with Peter Bosted, to gain from his experience
    - PB pion PID cuts -> aero npe > 4.0, aerogel eff ~96% for both indices of
      refraction
    - PB noticed some SIMC bugs in implementation of detector sizes and 3/4
      trigger
      - he turns off the detector-ALL flag to avoid the bug

- *Suggestions*
  - Gaskell: we should fix the routine instead of turning off the flag!
    - in addition, DG is a bit puzzled that PB found sensitivity to this issue,
      as other SIDIS analyses haven't been sensitive to it

  - PB has an HMS x-tar data offset of 2.7mm (vertical position of beam on
    target) but doesn't have any offset in SIMC

- *Suggestions*
  - Gaskell: by default hcana uses BPM information to calculate focal plane
    quantities (e.g. delta).  If BPM wrong, then delta wrong a bit too.
    - DG is puzzled that it's only for HMS and not SHMS
    - we don't necessarily have to follow PB's path, but we should learn from
      him and decide our own solutions

- *Task for AU*
  - Ali should ask PB for an example SIMC input file

Goals for Next Meeting
----------------------
- Heep-COIN analysis from Richard and Ali
  - Vijay will clean up singles Heep script
- Vijay looking at low Q^2 data SIMC comparions
- Nathan hoping for new FADC deadtime plots
- Junaid will show some detector calibration plots

Next Meeting
