SURFACE ANALYSIS: The following parameters are appropriate if fiducials are all on one surface Fit of one plane to all fiducials: Adjusted slope = -0.1654 Incremental tilt angle change = 9.39 Total tilt angle change = 9.87 The following parameters are provided to indicate the consistency of the fit when fiducials are on two surfaces Fit of one plane to points on bottom surface: # of points = 7 Z axis intercept = -59.21 Adjusted slope = -0.1851 Mean residual = 23.237 X axis tilt needed = 5.50 Incremental tilt angle change = 10.49 Total tilt angle change = 10.97 Fit of one plane to points on top surface: # of points = 14 Z axis intercept = 40.95 Adjusted slope = 0.0494 Mean residual = 5.773 X axis tilt needed = -0.43 Incremental tilt angle change = -2.83 Total tilt angle change = -2.35 The following parameters combine the last two results and are appropriate if fiducials are on two surfaces Thickness at Z intercepts = 100.15 Average adjusted slope = -0.0288 Average X axis tilt needed = 1.55 Incremental tilt angle change = 1.65 Total tilt angle change = 2.13 Unbinned thickness needed to contain centers of all fiducials = 145. Incremental unbinned shift needed to center range of fiducials in Z = 9.1 Total unbinned shift needed to center range of fiducials in Z = -17.5
