<u><b>James:</b></u> Looking at tracking with Bdl using physics angle
corrections. Using Bdl from Oscar. Hovhannes mentioned that this is
significantly different from BdL obtained via GEANT. The physics theta
appears to have a dependence on magnetic field, due to the phi being
affected by the magnetic field. This is most prominent in the lower
energies. Hovhannes will post his Bdl on the SANE wiki page.<br>

Calculating perpendicular asymmetries using position cuts. Essentially
divided BigCal in to 4 parts; RCS and Protvino, left and right. Jon
will provide efficiency maps (theta vs. phi) for these runs/run-ranges
to use for this.<br>

<u><b>Hovhannes:</b></u> Following up from last week, looked some more
at positrons binning in theta and fixing energy. The ratio of e+/e-
seems to be fairly constant as function of energy. The net number of e+
increases with angle, but so does the electrons. Will discuss with Mark
and Oscar.<br>

<u><b>Jon:</b></u> Following up from last week, almost finished with
cluster-energy resolution study, mentioned last week. The pion peak
seems a little off. Hovhannes will help with applying angle corrections.<br>

<u><b>Whit:</b></u> Using database, set up interface that provides
diagnostic plots relevant to detectors for each run. This would provide
a quick sanity check.<br>

<br>
As always, please let me know if I missed anything or if I made any
mistake(s).<br>
<br>
<br>
Next meeting will be October 13 at 15:30. During next week's meeting
the students who are giving talks at the DNP
in November will provide outlines for their talks to go over.<br>
