[Sane-analysis] Minutes of May 19 Analysis Meeting

[Narbe Kalantarians]

It seems that the GIZMO service has been discontinued in the way we were 
using it in the past. Will continue using the conference phone line 
until something better is available.
_*

John:*_ Added in reconstructed via neural network variables to physics 
Monte Carlo (pmc) ntuple. Narbe will check to see these and get checked 
into cvs. Got tracker and hodoscope variables to be written into GEANT 
ntuple. There is a problem with the tracker y1part (Narbe is looking 
into it).


_*Hovhannes: *_Has final constants for pi0 calibration for parallel 
data. Will get it checked into cvs. Working on correction for discreet 
block centers to get better agreement between generated and 
reconstructed (block) energy, and position. This correction will be more 
significant at lower energies (0.5-near 1GeV).


_*Oscar:*_ Looking at reconstructed physics angles. Comparing angles 
reconstructed with polynomial correction to angles calculated from 
cluster(s). Sees reasonable agreement, especially at center. Washing out 
is from energy dependence.

_*James:*_ Looking at particle tracking; physics angle projection to 
tracker. Seeing possible indication of electron-positron pairs at lower 
energy (<1.3GeV). Will look with separating of top and bottom of 
calorimeter (RCS and Protvino blocks) as well as junction of the 2 
block-types.

As always, please let me know if I have missed something or mentioned 
something incorrectly.

Will meet again next week (May 26th). Mark, Oscar, and Narbe will meet 
with Hoyoung and Seonho next week as well.
