    keyword=X = -1mm, HARP scan

    We move the beam to X = -1 mm
    EPICS says, X,Y = -1.0, 0
    Spot says -1.5, +0.5 (calib. seems off)
    Harp scan (plot below), run 1174 (73 was junk). CODA run 2010

    Survey offsets: X(5)=-0.07 Y(5)= 0.08 X(6)=-0.45 Y(6)=-0.23 mm
    dz4A = 7345.00 dz4B = 2214.00
