    keyword=y-tg no big peak with reduced raster size.

    MCC had raster FSD fault when trying to get raster size of 0.7x0.7mm.
    After consulting Chris Cuevas, he advised MCC to lower the threshold
    by changing input of beam current. After that MCC is able to give us 0.7X0.7mm
    (about 1x1mm from spot++). The new Y-tg plot shows clear improvement
    (no big peak at the upstream window).
