Beam setting for the Moller measurement took more than an hour because of
the off-center regular beam alignment. In Y, the regular beam position is
about 2.5mm. After the quads' settings were changed the beam went off by
10mm in the BPM 4B.
I measured the beam polarization with 4 different targets and got a
consistent result of +88.2%. The stat error is about 0.15%. The result is
preliminary - I have to look for the exact target polarizations at the
positions used.
