    keyword=Target motion during warmup and cooldown

    Target motion during warmup and cooldown:

    Two scope were set: First one set at beam left 90 degree.
    Second one initially was at beam right 45 degree and later moved to
    down stream. Target in loop 3 top cell (LD2_4cm) to have the survey
    targets visible.
    The motion after warmup and cooldown: target moved z: downstream 2.5 mm
    and x: beam left 0.5 mm, y: vertical down 0.5 mm (all with uncertainty of about 0.5 mm).
    (Only warm-up motion: z: downstream 1.5 mm, x 0mm, y down 0.5 mm; also all numbers have uncertainty of 0.5 mm).
