Follow up to Sal's Z AN presentation regarding the fitting of the asymmetry

Email form Sal:

following up on our discussion at our last meeting, I fitted the A_N asymmetry for Z0 production again but this time letting the offset running as a free parameter. As I expected I get similar results in terms of the amplitude. Not I also get an offset that is withing a sigma from zero.

Asymmetry fit:

Run 17 Z AN

Run 11 compared to Run 17 Z AN
