[Sane-analysis] Minutes of August 18 2010 Analysis Meeting

[Narbe Kalantarians]

_*Narbe:*_ Looking at resolution via pi0 mass peak. Using unaltered 
reconstructed energy, saw a resolution of about 1%. Applying a shift of 
9%  gave a  smeared resolution of about 6%. Increasing the shifting to 
12% produces resolution of about 9%, which is what is  seen with the data.

Going to study width of pi0 mass peak a function of (reconstructed) energy.


_*Anusha:*_ Looking at BPM projected vertical target position. Using 
this to get offset to apply to analysis for run #'s.

Almost finished with drift maps for HMS DC's, accounting for periods 
with significantly different  efficiencies. Going to have Mark verify 
this then send to Jon to use for Replaying data.

It should be noted that these items--especially the Ty offsets--could 
affect the packing fractions.


_*James:*_ Looking at dead-times from helicity scalers. Comparing these 
with asymmetries and half-wave plate status as function of run#.

_*Hohvannes:*_ Writing note for artificial neural network. Will send 1st 
draft to mailing list soon.


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

Next meeting will be Sept 1st at 15:30.
