Comparison with Elastic Deuteron Asymmetry
I calculated the size of elastic deuteron asymmetry that would correspond
to our experimental setup, assuming that where would be vector-polarized
deuterium in the target instead of Helium. To be able to compare these
results to our measured asymmetries, I corrected the elastic asymmetry for
the effective polarization of the (d) inside 3He (P = 2/3). I have
considered "Abbotts" parameterization of the (d) form-factors. I derived
the asymmetry formula using notes from ZLZ thesis. Here I considered
that Pzz (tensor polarization is 1).
Please see my notes for more details:

Following plots show 12.5deg and 14.5deg data, that were considered in the analysis.

Theta* and Phi* angles
By using additional event cuts (taking only those events for which theoretical calculations exist)
mean th* and phi* angles have changed a bit.
12.5deg data:

07.) 
14.5deg data:

How non-zero phi8 angle affects the asymmetry?
These plots show, how the theoretical asymmetry changes by changing angles th* and phi* around
the nominal values. Changes are not significant.
