|
-------
|
|
18
|
- meeting with Casey re. ifarm job system (swif)
|
|
19
|
- trying to merge his work with hcswif
|
|
20
|
- Stephen's scripts dynamically allocate disk space & memory, while hcswif
|
|
21
|
has these hard coded
|
|
22
|
- hcswif allows for run# ranges, as opposed to specifying each one
|
|
23
|
individually
|
|
24
|
|
|
25
|
- updates to hcana
|
|
26
|
- looking into putting singles trigger assignments into a PARAM file instead
|
|
27
|
of hard coded
|
|
28
|
- will be called HMS, SHMS instead of TRIG1, TRIG3, etc
|
|
29
|
- adding raw untracked COINTIME variable, for untracked analysis
|
|
30
|
- Mode-10 stuff is already included
|
|
31
|
|
|
32
|
- cleaned up UTIL_BATCH
|
|
33
|
- divided into different run periods
|
|

|
|
37
|
- Analysis Plan
|
|
38
|
- divided up Heep-COIN and Heep-SINGLES runs with Richard
|
|
39
|
- fine tune efficiencies and offsets
|
|
40
|
- discussed things with Peter Bosted, to gain from his experience
|
|
41
|
- PB pion PID cuts -> aero npe > 4.0, aerogel eff ~96% for both indices of
|
|
42
|
refraction
|
|
43
|
- PB noticed some SIMC bugs in implementation of detector sizes and 3/4
|
|
44
|
trigger
|
|
45
|
- he turns off the detector-ALL flag to avoid the bug
|
|
46
|
|
|
47
|
- *Suggestions*
|
|
48
|
- Gaskell: we should fix the routine instead of turning off the flag!
|
|
49
|
- in addition, DG is a bit puzzled that PB found sensitivity to this issue,
|
|
50
|
as other SIDIS analyses haven't been sensitive to it
|
|
51
|
|
|
52
|
- PB has an HMS x-tar data offset of 2.7mm (vertical position of beam on
|
|
53
|
target) but doesn't have any offset in SIMC
|
|
54
|
|
|
55
|
- *Suggestions*
|
|
56
|
- Gaskell: by default hcana uses BPM information to calculate focal plane
|
|
57
|
quantities (e.g. delta). If BPM wrong, then delta wrong a bit too.
|
|
58
|
- DG is puzzled that it's only for HMS and not SHMS
|
|
59
|
- we don't necessarily have to follow PB's path, but we should learn from
|
|
60
|
him and decide our own solutions
|
|
61
|
|
|
62
|
- *Task for AU*
|
|
63
|
- Ali should ask PB for an example SIMC input file
|
|
64
