_*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.
https://hallcweb.jlab.org/experiments/sane/wiki/index.php/Raw_Asymmetries#First_Glance_at_Runs_72400-72700:_2.2F23.2F2011
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.
