Regarding Oscar's study, a corrected/updated version of his note is
posted in his directory<br>

<u><b>James:</b></u> Began a table listing runs to be used for
analysis. The format is logic-style. Adding runs as they get replayed.
Using gscalers 510 and 538 for the live-time. Will switch to the
510*(513+514)/505 as determined by Hovhannes.

Will add a column for number of events and also one for comments.<br>
Starting to work on radiative tail with Karl.<br>

<u><b>Oscar:</b></u> Did a study of the false asymmetries. Referring
to
James' study where he swapped the definitions for charge-normalization

Mark looked further in to this and found that this can't really be done
because it produces an inconsistency int the labeling. Using Mark's
model for the live-time. Posted the spread-sheet in the same directory
where his note is posted.<br>

<u><b>Luwani:</b></u> Plotted asymmetries for neutral pions with
P_Beam*P_Targ. There seems ot be a dependence on P_Beam*P_Targ, similar
to what is being seen for the physics asymmetries.<br>

Will plot pi0 asymmetries with both of these corrections together, and
try grouping P_Beam*P_Targ by average.<br>

<u><b>Narbe:</b></u> Set the SANE GEANT to have outside liquid helium
on the edges of the target cup. Got this working shortly before the
meeting and running the MC to get statistics to check for effect on
dilution factors.<br>
Began using Peter Bosted's radiative corrections code for the BETA
kinematics.<br>
<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 April 13, 3:30pm JLab time.<br>
