The top right section of the Best Fit Dialog displays the fit results.
These results will be invalid (and therefore will have a dark blue background) whenever the best-fit solution has either not been solved or a change has been made since it was last solved. The fit results table contains, on a component-by-component basis, several statistical values related to the fit that help you determine how well the fit performs. These values include:
Count. The number of points included in the fit for the specified component.
Max Error. The maximum error between a pair of corresponding points. This is an indicator of the “worst fit” for any pair of corresponding points.
RMS Error. The root-mean-square error of the fit as a whole. This is a good indicator of the overall error of the fit. This number is always less than or equal to the max error (although usually it’s noticeably smaller than the max error).
StdDev Error. The standard deviation of the errors. A small value indicates that each pair of points had similar errors. A large value indicates that one or more error values differed significantly from the group as a whole.
Max Error (all). This is the same as Max Error, except all points are included (even those which are deselected from the fit).
RMS Error (all). This is the same as RMS Error, except all points are included (even those which are deselected from the fit).
Translation. The x, y, and z instrument translation needed for the solution.
Rotation (Fixed YZ). The instrument rotations required for the solution, in Fixed XYZ form.
Rotation (Euler XYZ). The instrument rotations required for the solution, in Euler XYZ
Rotation (Angle axis). The instrument rotation required for the solution, in Angle axis form (first three values describe the rotation axis, and the last value describes the rotation angle).
Scale Factor. The scale factor applied for the fit. This will be 1.0 unless the Scale degree of freedom is checked (allowed to float).
Matrix. This is the 4x4 transformation matrix that will be applied to the instrument.
