Beam conditions: 2.134 (accel) , Wien angles -72.0o.
1/2 wavelength plate was IN.
The beam polarization:
Pz= 72.5+/-0.2(stat)+/-3(syst)%. - no leak through correction.
Pz= 74.7+/-0.2(stat)+/-3(syst)+/-0.5%(leak)%. - with the leak through correction.
The leakage from Hall C, working at 50µA was about 2.0%,
at Hall A slit position of 13.5, att=600.
