<u><b>Hoyoung:</b></u> Got set up and produced packing fractions for
some parallel field HMS data. Will proceed to get remaining packing
fractions as well as dilution factors for parallel runs.<br>

<u><b>Anusha:</b></u> ep elastic analysis. With latest calibration
constants from the neural network, the elliptical cut had to be
altered. This recovered the ep elastic events along with some
background. Will work on adjusting this as needed.<br>
<br>
<br>
<u><b>Hovhannes:</b></u> Showed plots of parallel BETA asymmetries for
the case of using the helicity scalers with the nominal polarity as
well as switched. The dead-time distributions are over all the runs
combined. Will look at deadtime asymmetries as a function of run#. <br>

<u><b>James: </b></u> Calculated online target polarizations corrected
by proper Yale Gain card and offline TE values. The deviations in the
Offline/Corrected Online ratios correspond to the cases of polarization
drifts and varying polyfit areas. Also produced data files. <br>

<u><b>Jon:</b></u> Looked at distributions of Cluster energy as
function of x,y position and (azimuthal) phi. Saw some non
uniformities. Oscar saw similar results making his own plots. Hovhannes
mentioned that secondary peaks could be coming from non triggering
particles, since the gain-matching is not the same across BigCal for
all the blocks and therefore the threshold is differing. Also, that the
block size is different. For phi<0 the blocks are 3.8x3.8 cm2, while
for phi>0 they are 4x4 cm2, resulting in different (5x5) cluster
sizes. For the plots of E_clust vs phi there are some spikes, which
could be from the fact the energy calibration is huge for some blocks
,possibly due to large background, and might require some default
values. Oscar suggested looking at these distributions with the SANE
GEANT, which Narbe and James will do. It would also be useful to look
at the energy distributions in bins of phi. <br>
