<u><b>Narbe:</b></u> Produced dilution factors with corrected radiative
corrections (not post-target radiating twice, only with GEANT), and
components being accounted for correctly. This is with limited
statistics, but will let James and Jon use as input for asymmetries
until more statistics are accumulated.<br>

<u><b>Luwani:</b></u> Looked at pi0 asymmetries with newly replayed
ntuples. Sees hint of an asymmetry for parallel, but with large error
bars, due to low statistics. <br>

Will make tables of these asymmetries sorted by energy, target field,
...<br>

<br>
<u><b>Oscar:</b></u> Posted a writeup on background asymmetries and
dilution, going over how the expression is derived.<br>

<u><b>Hoyoung (02/23/12):</b></u> Looked at one of the runs giving
really huge packing fractions (72213), comparing to run giving
reasonable packing fraction (72828), using the same target
material/load. Normalizing to charge, gives a ratio fairly close to
unity (~1.05). Oscar asked if BCMs might be an issue, considering
that they may not have been calibrated well enough for the early runs. <br>

Will try a couple of things: <br>
1) Try running MC with 70% PF for input and see what happens
interpolating 50 to 70% instead of the usual 50 -60%<br>
2) Scale the PF for 72828 with the ratio of yields (Y_72213/Y_72828) to
use as a PF for 72213.<br>
<br>
Posted a draft of his talk for the collaboration meeting, going over
HMS asymmetries and some on PF's<br>

<br>
As always, please let me know if I missed anything or if I made any
mistake(s).<br>
<br>
Next meeting will be February 29th at 3:30 PM (JLab time).<br>
