Integral Delta G Study

 Using Werner's code I calculated A_LL for pi0 production over my eta range for 15 different integral values of Delta G.  Below I plot the measured A_LL points and all of those curves.

I then calculated chi^2 for each of the curves.  Below is the chi^2 vs. integral delta g.

The red line shoes minimum chi^2 + 1.  For my points, GRSV-Std exhibits the lowest chi^2, but GRSV-Min is close.  My data indicates a small positive integral value of delta g in the measured x range.
