<u><b>Hovhannes:</b></u> Did a write-up of his asymmetry calculations,
focusing on how to handle the scaler information, especially pertaining
to the perpendicular-field data. It seems that the perpendicular-filed
data might need ot be treated somewhat differently than the
parallel-field data.<br>

Will try these methods on parallel data for accidentals(outside of
timing and no good Cerenkov), then look at ratio of reals to
accidentals.<br>

<u><b>James:</b></u> Posted a copy of the seminar he gave at UNH this
past Monday (Feb 7th).

Made pictures/figures, relevant to target, to use for talks.<br>

Made tables of updated target polarizations with cuts on beam current
(I_Beam > 50nA and 60nA). Sees a slight difference in between these
2 cuts. <br>
<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Final_Target_Polarization#Current_cuts_at_50.2C_60_nA:_2.2F9.2F2011">https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Final_Target_Polarization#Current_cuts_at_50.2C_60_nA:_2.2F9.2F2011</a><br>
Applied these cuts to the asymmetries. Though, the target polarization
will get updated to the tables just mentioned.<br>

<u><b>Anusha:</b></u> Made plots of xtar, xptar, ytar, yptar, and
deltaP_HMS vs W. This was done with the MC she has been using. Doesn't
see correlations as before. These seemed to be fro ma bug in her code
that she corrected.<br>

Will compare with HMS data.<br>
<br>
<br>
<u><b>Narbe:</b></u> Updated on BETA dilution factors effort. The df is
high for the W region near elastic, due to there being extra counts at
low W. Working on figuring this out.<br>

Will redo using bins from generated tables, as well as sort in to Q^2
bins.<br>
<br>
<br>
<u><b>Luwani:</b></u> Continuing to look at pi0 asymmetries for run#.
Will add on the error-bars. Oscar mentioned that there could be
correlations with the (inclusive)electron asymmetries.<br>
<a class="moz-txt-link-freetext" href="http://www.jlab.org/~lzwano/pi0_asy.png">http://www.jlab.org/~lzwano/pi0_asy.png</a> <br>
Will look at the rates.<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 February 16th 3:30pm JLab time.<br>
