    keyword=optics tuning

    We completed optics tuning: starting from HRS_r=3.15 GeV/c, Septum=403.75A,
    y_targ was -7 mm (with cut on the central hole).
    At HRS_r=3.10 GeV/c and Septum=409 A, y_targ is centered. This will be our tune.
    Note it is a nearly 3% difference from the expected tune. Not sure if it is due to saturation. We need to check at each momentum setting the y_targ position with single 12C foil.
