[Sane-analysis] Minutes of December 14 2011 Meeting

[Narbe Kalantarians]

_*Narbe:*_ Increased kinematic bin widths (essentially doubled) to 
account for resolution seen from data.  Looked at some dilution factors 
with these bins to check.

Working on comparing df's fro mGEANT with df's calculated directly from 
model.


_*Anusha:*_ Comparing data/MC, scaling the Form Factors model in the 
radiative corrections. This seems to have an effect. The inelastic part 
still seems underestimated in the MC. Using the total cross-section. 
Will try with cross-section by separate parts (elast, q.e., inelastic) 
and scale inelastic directly.

_*Whit:*_ Looking at pi0 reconstruction, comparing data/MC. This is for 
5.9 GeV parallel. The generator for this is using the Wiser code. In 
process of gathering statistics and fixing bug(s).

_*Oscar:*_ Update on comparison of data ( asymmetries' denominator) and 
df's from MC. Weighting by bins gives more agreement. This is with 4.7 
GeV parallel. The df's are with pf=0.68, while the data is averaging 
over several pf's.

_*Hoyoung (12/15/11):*_ Updating pf's with corrected HMS replay. Carbon 
data/MC seems to have improved. Revisited the previously (very)large 
pf's (runs 72984 & 72991)

With the corrected replay, these go down few percent to more reasonable 
values. These are in progress.

As always, please let me know if I missed anything or if I made any 
mistake(s).

Next meeting will be December 21 at 3:30pm (JLab time).
