All Shift Measurements and Angles Are Reported in Millimeters, and Radians, Respectively. The Shift Column Describes the Total Shift of the Target Point. The STE Column Describes the Shift Tracking Error of Protocol on This Point. The Θ Column Describes the Deviation of the Calculated Shift Vector From the Measured Shift Vector. A Perfect Tracking Would Produce Low STEs and Θs
