<u><b>James:</b></u> Updated beam polarizations, adding in information
for 1/2-wave plate and Wien angle. Talked with Dave Gaskell , who will
update the fit.<br>
Looked at raw asymmetries , factoring in beam&target polarizations
and dilution factor, based on packing fractions from a particular HMS
setting (parallel, 3.2GeV, 20.2degree). This gives a preliminary
physics asymmetry A_parallel, per run. The dilution factor is more
valid for DIS region than resonances. Oscar suggested taking a weighted
average of packing fractions for further study of the asymmetries. Will
try applying dead/live-time corrections and start with kinematic
binning, startign with 1.9<W<3.0 region. Planning on finalizing
target polarization calculations i.e., the errors for calibration
constants.<br>

<u><b>Oscar:</b></u> Doing qualtiy checks for the asymmetries. Looking
4.7GeV parallel asymmetry distribution, checking errors and chi-square.
Sees a non-Gaussian/non-symmetric distribution per bin for asymmetry
value.<br>

Applied off-line beam and target polarizations to update FOM. Sent
e-mail yesterday regarding this:<br>
<br>
"As a result, the total FOM hours have increased by 18, dominated by<br>
the 5.9 GeV 80 deg increase of 10 h. Since the online live time numbers<br>
I was using have been superseded, redoing the FOM with off-line values<br>
is pending the full replay of all runs with the latest analyzer.<br>
<br>
A new table is posted on the wiki under "Analysis", "Updated run<br>
summary", for use in future talks, reports, etc.<br>

These should be the numbers to use in talks from now on.<br>

<u><b>John:</b></u> Looking at lucite efficiencies and comparing
measured with expected, where expected is projecting from tracker +
BigCal. Efficiencies = information from lucite / information from
x,y_clust appear to be lower than expected. Will look further into
this. For resolution, taking difference of measured - expected.
Apparent double-peak for y_diff consequence of lucite_y being integer
in value, giving jump (resolution issue). Working on getting efficiency
for lucite_y for each bar.<br>

<u><b>Luwani: </b></u>Looking at cluster energy distribution (e_clust)
for photons and electrons. Isolating electrons and photons by cutting
cer_h>0,=0, respectively. No trigger-type cuts applied right now.
Working on isolating pi0 events, by reconstructing pi0s similar to what
Hovhannes did.<br>

As always, please let me know if I missed anything or made a mistake.<br>

Next meeting will be July 28th.<br>
