Beam conditions: 4.210 (accel) , Wien angles -20.0o.
1/2 wavelength plate was OUT.
The beam polarization:
Pz=-60.2+/-0.2(stat)+/-3(syst)%. - no leak through correction.
Pz=-65.2+/-0.2(stat)+/-3(syst)+/-0.5%(leak)%. - with the leak through correction.
The leakage from Hall C, working at 88µA was about 5.2%,
at Hall A slit position of 14.28, att=600.
The spin angle in Hall A is large (about 40 deg).
