The Best Fit (BF) and Best Fit Recompensate (BFRE) constructed planes have the option of filtering the deviations of the measured data points from the best fit plane computed from the measured data.
Apply Gauss Filter - If you select this check box, PC-DMIS applies a Gaussian filter with a cutoff wavelength. Generally, a larger cutoff wavelength produces smoother filtered data.
Remove Outliers - If you select this check box and you are filtering the data, PC-DMIS removes outlier data prior to filtering. For additional information on Gaussian filtering, see the "Gaussian" topic under "Constructing a Filter Set".
