_*James:*_ Took a detailed look at the 5.9 GeV parallel B-field runs
that are have the systematically different symmetries. Looked at
relevant parameters. Reached a consensus that the (NMR) coil might have
moved, due to material moving possible from radiation damage. Will look
at function of charge to rule out beam loss.

_*Narbe:*_ Update on dilution factors for BETA. Looking at 4.7 GeV
parallel B-field runs using their nominal packing fractions from the
table. Using SANE binning. Also using same energy cuts as for
asymmetries. Seem reasonable. At higher energies there seem to be less
radiative corrections. Will look at remaining pf's.

_*Whit:*_ Looking at asymmetries as function of Cerenkov mirror, and
also for different energies. Replay is still in progress for some of the
runs.

Fixed P_B*P_T for (parallel B-field) asymmetries.

_*Hovhannes:*_ Looking at physics asymmetries A1 and A2. Polarizations,
df's(w/ rc's), and elastic tail rc's applied. Using his proposed method
for A_90 (See agenda for August 31, 2011). Also using SANE bins and
energy cuts. Sees a good amount of consistency.

As always, please let me know if I missed anything or if I made any
mistake(s).
Next meeting will be September 21, at 15:30(JLab time).
