We measured the beam geometry on HAM6 after the rotation of the septum window.
The new beam is actually going up by 1.9mrad, in stead of previous going down by 4.3mrad.
The beam height entering HAM6 is too low from the beginning, this upward angle gives us
the right height of the spot on OM1 in sub-milimeter presicion. In the horizontal projection,
The new beam is almost overwrapped with the designed path.
