Greetings,
I have solved the G12 normalization. I do not know the cause, but I know
the fix. I performed my study using 3 topologies:
1) Proton Pi+ missing Pi-
2) Proton Pi- missing Pi+
3) Pi+ Pi- missing Proton
I skimmed data and phasespace MC alike. I then looked at the efficiency
of reconstructing the missing particle via missing mass techniques. Once
the particle was reconstructed, I compared the reconstructed values of
the missing particles to when the reconstructed particle was detected in
CLAS.
I then binned each topologies into bins of MVRT z, momentum, theta/phi
for both data and MC.
The study showed that the MC was over efficient. I applied a correction
according to the efficiency mapping I created and preformed the
XSection study.

for comparison plots of the static normalization to a dynamic efficiency
normalization.
