<u><b>Anusha:</b></u> Followed up on applying azimuthal corrections,
using the suggested procedure:<br>
<br>
1) Correct ytar with the slow-raster x and y offsets.<br>
2) Correct for any correlation(s) between xptar and mass of final
states W via azimuthal correction.<br>
3) Fix any remaining offset in data/MC for xptar with slow-raster y
offset.<br>
4) As a check, see that there isn't any correlation between xptar and
yptar.<br>
<br>
Looking at perpendicular field runs (72783-72803). Sees improvement,
but there remains some correlation between xptar and W. <br>

Will look run by run, especially the beam offset, to see if this is
constant or time dependent. Will also check parameters used in
azimuthal correction. <br>

<u><b>Narbe:</b></u> Follow up to dilution factors for BETA. Found a
mistake in the error calculation, which was underestimating them.
Errors improve some, but still not sure if the functional form is
correct. There are still some fluctuations in the dilution factors.
This could be due either to the H2 not being accounted for correctly or
the (mentioned) error calculations.<br>

Still looking in to the details.<br>

<u><b>Luwani:</b></u> Looking at the neutral pion asymmetries using the
more recent replay of Hovhannes' to compare with those he obtained
using the official-Octavian replay.<br>
<br>
<br>
As always, please let me know if I missed anything or if I made any
mistake(s).<br>
<br>
Next meeting will be August 17th at 3:30pm, JLab time.<br>
