<u><b>Hovhannes:</b></u> Going through procedure for calculating

positive helicity scalers, based on work done by Oscar and Hoyoung.

Compared Hoyoung's method of fitting-areas to fitting-centroids. <br>

<u><b>Narbe:</b></u> Looked through radiative corrections code. Turned

off smearing for elastic peak and test ran one of the Q^2 bin generated

kinematic tables. Seems to get reasonable elastic cross-sections.<br>

<br>

Added structure-function F_1 and R(=sigma_L/sigma_T) to GEANT ntuple.

Will be used to make tables for physics asymmetries. <br>

Because the models are per nucleus, will need to make sure F_1 and R

are from proton and not NH3(nitrogen or helium).<br>

<br>

<br>

<u><b>James:</b></u> Working with Jonathan on getting A_1 and A_2.

Using abridged ntuples via Jonathan's code. <br>

<a class="moz-txt-link-freetext" href="https://hallcweb.jlab.org/experiments/sane/wiki/index.php/A1%2C_A2_and_Structure_Functions#First_look_at_A1.2C_A2">https://hallcweb.jlab.org/experiments/sane/wiki/index.php/A1%2C_A2_and_Structure_Functions#First_look_at_A1.2C_A2</a><br>

<br>

<br>

As always, please let me know if I missed anything or if I made any

mistake(s).<br>

<br>

*** There <i>won't</i> be a meeting next week, so the next meeting

will be May <i>18</i>th 3:30pm, JLab time.<br>
