<u><b>James:</b></u> Looking at lifetime polarizations of target
material. Plotting polarization as functions of dose and time. This is
to look for any other periods of strange polarization that was seen for
a few of the parallel B-field runs.<br>
<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Final_Target_Polarization#Material_Lifetime_Polarizations:_10.2F19.2F2011">https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Final_Target_Polarization#Material_Lifetime_Polarizations:_10.2F19.2F2011</a><br>
<br>
Updated the polarization table. Corrected/updated some of target
polarizations after applying/fitting a "general" decay curve. Will look
with average of decay curves.<br>

<br>
Updated calculations of kinematic coefficients for physics asymmetries
A_1,2. Has a bug that is overestimating the errors. <br>

<br>
Applying (elastic) radiative tail corrections per bin, per run. <br>

<br>
<u><b>Narbe:</b></u> Updated kinematics tables using Q^2 with dynamic
width (+/- 15%) instead of the fixed +/- 0.5GeV widths.<br>

<u><b>Whit:</b></u> Implementing helicity-dependent cross-sections for
his event generator. <br>

<br>
<br>
<u><b>Luwani:</b></u> Started using the GEANT-MC for looking at pi0
production/rates to compare with data. <br>

<br>
<br>
<u><b>Hovhannes:</b></u> Revisiting positron contribution for data at
lower E' (E' < 1.1 GeV). Sees some dependence on (polar) scattering
angle theta. Limited statistics at large angles. Looking at counts vs.
(projected - reconstructed), projected is obtained from target (SR_x,y,
theta, phi) then interpolated to tracker. <br>
<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/bhovik/Pos_Cont/">https://hallcweb.jlab.org/experiments/sane/bhovik/Pos_Cont/</a><br>
Will compare with Eric and Peter's model for positrons, which uses JLab
data.<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 October 26, 3:30pm (JLab time).<br>
