After our finding that both spectrometers see y-target offset, Meekins goes and looks
at the target after we go to restricted access. He finds that the target is significantly
skewed relative to the beam, in both vertical and horizontal planes. A survey
will be done to give us better information on this. The couple cm offset appears
to be real.
It is likely that this is the cause of some larger than expected backgrounds,
and narrow apertures during the run. (Ref: JP target moving tests of ~4 mm aperture.)
And apparent beam tuning problems and variations, of course.
