Beam conditions: 3.362 GeV, linac = 0.550 MeV, Wien angle 8.1o.
The beam polarization: -67.4+/-0.2(stat)+/-3.0(syst)%.
Mott: 70.8% (see ELOG from Apr,6).
Cross-talk from Hall B laser was measured while Hall A laser was turned off.
It was about 0.001 of 0.25uA
at the tight slits. At widely opened (retracted) slits it became about 0.05.
We measured the polarization from Hall B laser to be +59.6+/-1.7%.
Hall A and B lasers now have opposite polarizations.
Hall B had measured their polarization as 60%.
