<u><b>Hovhannes:</b></u> Tried using (BigCal + Cerenkov TDC) timing cut
in place of geometric cut for BigCal signal. Using the timing cut in
addition to the geometric cut gives improved signal for BigCal TDCs. <br>
<br>
Looking at background asymmetries (no Cerenkov cut). Background
asymmetries seem to be significant in size, on same order as
asymmetries for the perpendicular data. This is a very preliminary
look and requires further investigation with varying cuts.<br>
<br>
<br>
<u><b>James:</b></u> Looked at drops in polarization due to drifting
(target) magnetic fields. <br>

The altered/improved shoulder fitting method mentioned previously seems
to work well. The only time it doesn't seem to work is in the case of
there being a hump on the peak. This is very rare, though, and only
occurs about 2 times for the parallel data.<br>

<u><b>Jon:</b></u> Looked at (raw counts) asymmetries for the 5.9geV
parallel data with varying cuts to understand what is causing the
structures over time. These cuts include varying slow raster size and
cluster energy. The higher cluster energies would cut out the lower
energy pair symmetric background. Some of the structures do appear to
be from background.<br>

<u><b>Narbe:</b></u> Got the SANE GEANT3 to work on Octavian. now
working on refining the reconstruction. Showed some reconstructed
values for outgoing electron to cluster for simulated 4.7geV parallel
setting. Needs to use cuts though (>10MeV per block and cluster
selection). Will compare thrown to reconstructed.<br>
