<u><b>Anusha:</b></u> Did data/MC comparison using azimuthal angle
correction. Applying it alone and w/o any slow-raster offset gives some
improvement. Adding a SRx offset seems to give the best improvement.
Adding a SRy offset seems to over-correct, possibly from changing the
azimuthal. Will try applying SR x&y offsets before azimuthal
correction to see what happens. Will try these corrections with the
parallel Carbon data.<br>

<u><b>James:</b></u> Write-up of elastic radiative tail correction. In
process of finalizing it. Will start applying this to asymmetries.<br>

<u><b>Jon:</b></u> Put together a routine for the physics ntuples to
produce skimmed ntuples for the primary physics analysis. In progress
to be finalized. Tested and got asymmetries consistent with what James
is getting.<br>

<u><b>Luwani:</b></u> Revised draft of talk for PAS meeting this
Saturday (04/30/11).<br>

<u><b>Oscar:</b></u> Looked at false asymmetries from carbon runs.

Tried many combinations/permutations<br>

And got some interesting results<br>

<u><b>Hoyoung(04/28):</b></u> Looking at deadtimes. Added total
trigger, equal to gscaler_change(510), to replay code and written in to
chargetemp.dat file. Working on minimizing the false asymmetries from
Carbon data by fitting the correlation between the trigger and scaler
and then looking at the chi^2 relative to degrees of freedom. Gets
answers fairly similar to Oscar's. Tried applying to NH3 data. Will
work on cross-checking with Oscar.<br>

As always, please let me know if I missed anything or if I made any
mistake(s).<br>
<br>
Next meeting will be May 4th at 3:30pm JLab time.<br>
