[Sane-analysis] Minutes of June 2 Analysis Meeting

[Narbe Kalantarians]

_*Hoyoung:*_ Working on tracking efficiencies. Looked at scintillator 
efficiencies, which is uniform. Will look at drift chamber efficiencies 
for tracking and x-position dependence. Will use DC efficiency with (6) 
scintillator paddle positions to approximate delta. Will also try a cut 
on total calorimeter energy (hcal_etot) to restrict electrons to those 
that hit the calorimeter and avoid shower particles.

_*Narbe:*_ Looking at acceptances from GEANT-MC to determine binning. 
Looked at W distribution with Q2 bins for parallel and perpendicular 
settings. Acceptance appears to be larger for parallel, but resolution 
seems more pronounced with perpendicular. Will try looking with no field 
setting to compare. Looked at Scattered vs. Azimuthal physics angles; 
both being polynomial corrected for field. Sees remnants at lower 
(reconstructed) energy bins. Will compare with uncorrected.

_*Anusha:*_ Prepared poster for JLab users' group meeting. Looks forward 
to comments/questions to get poster revised and submitted by this Friday 
(June 4) at 10:00am.

_*Jon:*_ Working on Physics MC (PMC) code. Replacing old cluster routine 
with what is done in Replay Engine.


_*James:*_ Working on projecting tracks from target on to BigCal and 
looking at tracker information. Using this to check field corrections. 
Sees position dependence with Protvino blocks. Also sees a difference in 
distributions in positive and negative x positions in Protvinos. Will 
look at scattering vs azimuthal for each of these sectors and also 
Cerenkov mirrors.

_*Whit:*_ Working on analysis software (InSANE). Set up a (MySQL) 
database at Temple, containing all configuration information for the 
data set. Going to try to get this built on Octavian.

As always, please let me know if I forgot something or made a mistake.


There will be no analysis meeting next week, due to the users' group 
meeting. Next meeting will be in 2 weeks (June 16th).
