<u><b>Hovhannes:</b></u> Looking at pion contribution. Comparing data
and MC. There seems to be some energy dependence, and the MC predicts
more pions at higher energies. This could be due to the model being
used (Wiser). Adding more statistics. This contribution will also be
dependent on dilution factors.<br>

<u><b>Anusha:</b></u> Update to comparisons of data/MC. Looking at NH3
and deltaP vs W. It seems that opening up the deltaP cut/range gives
some improvement on the elastic peak position. Eric mentioned to use
some caution in increasing the cut/range, because going higher in
negative deltaP could result in hitting the can, plus the optics matrix
is not very well known for this. Will compare with C run(s).<br>

<u><b>Hoyoung(Dec 1):</b></u> Comparing data/MC adjusting the slit
position on the MC to get reasonable agreement with some of the HMS
runs where the slit was (partially) closed. Adjusting it to ~8.8cm
seems to give reasonable comparisons. Though, deltaP still doesn't
seem to look good. For the pf's, could try using region with reasonable
data/MC agreement (~ -5 < deltaP < 5). Also, C+He run 72442 was
an early run and parameters/settings (target position, drift-chamber
gases - efficiencies, ...) were not well established. Will look at NH3
runs, one each for top and bottom cup to check things. Starting to redo
packing fractions for the parallel data with the updated/corrected HMS
replay code. <br>

As always, please let me know if I missed anything or if I made any
mistake(S).<br>
<br>
Next meeting will be December 7th at 3:30pm (JLab time).<br>
