Beam conditions: 2.134 (accel) , Wien angles -72.0o.
1/2 wavelength plate was IN.
The beam polarization:
Pz=-72.1+/-0.2(stat)+/-3(syst)%. - no leak through correction.
Pz=-74.6+/-0.2(stat)+/-3(syst)%. - with the leak through correction.
The leakage from Hall C, working at 60µA was about 2.2%,
at Hall A slit position of 13.26, att=600. The Hall C polarization
Mott: (-71.0 +/- 0.7stat ) %
