ALS Fiber Polarizonation Check: < 10%, OK to GO
J. Kissel

ALS Fiber PLL's rejected/wrong polarization looks nice and low. The wrong polarization has swung up and down over the past 6 days, but never over ~20%. This is expected since the long-term drift is not controlled, and temperatures of the site have been dynamic. Currently hovering at a very acceptable ~7 / 4 % for X / Y, respectively. Trend attached.
