_*James:*_ Looked at applying different azimuthal-phi cuts along with
some scattering-theta cut on the parallel perpendicular field 4.7GeV
data. Gets very few events. Will try without (some of) the standard
cuts. The distributions are different for the 2 different field
configurations.

Varied the standard cuts to study the effect(s) on the asymmetries. Sees
that the asymmetries are driven by the low energy (<0.800GeV) events.

Started looking at the 5.9GeV perp asymmetries. Adding more statistics
as they finish replaying.

Will take out charge normalization for now.
_*Jon:*_ Also looking at 5.9GeV perp asymmetries, providing further
cross-check. Will post plots later on.
For the asymmetries, Mark mentioned taking into account the false
asymmetry seen from the Carbon data, which is on the order of ~-0.002.
For the PANIC, July 24-29, Whit and Narbe plan on presenting. They will
circulate copies of their abstracts before submitting.
As always, please let me know if I missed anything or if I made any
mistake(s)
Next meeting will be March 2nd 3:30pm JLab time.
