---------------
|
|
25
|
- Luminosity replays will be running soon
|
|
26
|
- Waiting on this from Ali, tracking updates needed
|
|
27
|
- Needed to fix some errors in report files
|
|
28
|
|
|
29
|
- Discussed with Bill over email regarding LT software, waiting for more info
|
|
30
|
|
|
31
|
- starting to generalize Heep script for Physics
|
|
32
|
- looking to implement t-binning similar to Alicia's work
|
|
33
|
- GH: Bill handles it in his LT separation code, should probably stay there
|
|
34
|
for Richard too. The idea is to read in the SIMC and Expt data for all
|
|
35
|
angles at a given (Q2,W) at once and handle them together. So there's no
|
|
36
|
advantage to put the t-binning before the LT code

|
- Met with Holly two weeks ago, another meeting tomorrow
|
|
41
|
- 6.8 GeV/c HMS matrix didn't seem very well optimised, trying to make
|
|
42
|
improvements
|
|
43
|
Run 14973: Central Foil. Run 14970: Multi-Foil
|
|
44
|
- HMS PolTar ME fit
|
|
45
|
- Very long target ME from A1n
|
|
46
|
- Actually does an OK job at -ve delta for the -8.0 foil
|
|
47
|
- Applied optimizations, so Three ME are studied:
|
|
48
|
1) Original ME 2) PolTar not optimized 3) PolTar optimized
|
|
49
|
- Xsieve holes resolve better after ME optimizations are applied
|
|
50
|
- some weird tilt in the holes at Ysieve ~4cm
|
|
51
|
- PolTar matrix is smaller than other matrices
|
|
52
|
- looking at to increase polynomial order in ME
|
|
53
|
- DG: use COSY to calculate higher order ME and start with that
|
|
54
|
|
|
55
|
- Will move on to looking at SHMS ME corrections soon
|
|
56
|
- Highest was ~8 GeV/c in SHMS?
|
|
57
|
- HB, Q1 saturation may play a role at higher momentum
|
|
58
|
- DG: weird correlations were observed between W_elastic & delta that Casey
|
|
59
|
had to remove from 2019 data, hopefully you don't find the same problem
|

|
|
62
|
---------------
|
|
63
|
- Looking to remove correlation between RFtime and CoinTime
|
|
64
|
- will push what he has to GITHUB soon
|
|
65
|
|
|
66
|
- Hall C workshop in January
|
|
67
|
- Agenda needs to be finalised a bit, a few talks planned
|
|

|
|
69
|
