keyword=Summary Compton photon asymmetryComparison of run 17165 - 17175 ( positive one ) and after source activation Run 17200-17205 ( negative one ).
Since the asymmetry is small and the data is raw the uncertainty is roughly 5 % systematic looking at the dispersion of the points, maximum asymmetry is around 1.6 slightly lower than previous average at 1.7, so hard to tell if polarization changed much at 5 % level. We have an asymmetry between left and right laser still need to understand that since it makes a large systematic for the maximum asymmetry. The first plot is average of left and right laser.
