    keyword=center beam position double check

    I use the position measured in the morning(A(+0.9,+2.1) B(0 +0.8)) and target offset to double check the beam position again by using the cross target(1 inch diameter), and the slow raster size is 2.1V. looks like the beam position is in the center.
