<u><b>Hovhannes:</b></u> Looking at (perpendicular)asymmetries using
the updated beam and target polarization tables. When applying the
target polarization some of the runs change signs, mostly when the
target polarization changes sign. This seems to be consistent with what
James and Oscar see when applying the half-wave plate status/correction
to both the beam polarization and the asymmetries. There was some
discussion over the idea of whether the target polarization sign might
be incorrect at times -James will check this. Will look at asymmetries
for each cup.<br>
Running quality checks: picking out runs with drastic change in
polarization.<br>
<br>
<br>
<u><b>James:</b></u> Updated charge normalization for his asymmetries
analysis. Using BCM1 and h- over BCM1 and h+ to make q ratio used in
the charge normalization (this is g513 and g514 in the scaler files).
Previously BCM2 was used (517 and 518).

Updated beam polarization tables, both w/ and w/o half-wave plate
status.<br>

Posted a draft of his talk for the Hall-C meeting, focusing on the
asymmetries analysis with some mention of the HMS analysis (inclusive,
packing-fractions/dilution factors). Got some suggestions to implement
and will send a revised copy.<br>

<u><b>Anusha:</b></u> Started on making the azimuthal angle corrections
for the target magnetic field.

Posted a draft of his talk for the Hall-C meeting, focusing on the
proton form-factor ratios with (elastic) asymmetries. Got some
suggestions to implement
and will send a revised copy.<br>

<u><b>Whitney:</b></u> Started a write-up on how to use his analysis
code<br>

Ran checksum on the SANE (raw)data and didn't find any problematic
files.<br>

Working some more on his online database, which produces diagnostic
plots for each detector. Oscar suggested this be used to look at some
of the specific runs that have been giving drastically different
packing-fractions for the same target loads.<br>

Will post a draft of his talk for the Hall-C meeting, focusing on the
detectors and neural network aspects.<br>

As always, please let me know if I missed anything or if I made any
mistake(s).<br>
<br>
Next analysis meeting will be January 12, 2011, at 3:30pm.<br>
