keyword=Calib of RWP for Chg Asy Fdbk
Calibration of RWP slope for Charge Asymmetry Feedback.
Beam halfwave plate OUT. Feedback temporarily off.
Parity run............RWP...............Chg Asy (ppm)
3406....................321..................12 +/- 22
3407....................370...............-457 +/- 18
3409 (no 8).........270..................662 +/- 20
3410....................400...............-362 +/- 26
3411....................295.................417 +/- 22
With some reservations, we reject run 3410. Resulting slope: -11.3 ppm/step.
If we had included 3410 the slope would be -9.3 ppm/step.
