#### Apply Gauss Filter / Cutoff Wavelength

The Best Fit (BF) and Best Fit Recompensate (BFRE) constructed lines have the option of filtering the deviations of the measured data points from the best fit line computed from the measured data. The Apply Gauss Filter check box is a Gaussian filter with the smoothing controlled by the cutoff wavelength. Generally, a longer cutoff wavelength produces smoother filtered data. If you've selected the Remove Outliers check box and are filtering the data, then outlier data is removed prior to filtering.

For 2D lines, PC-DMIS filters the deviations in a plane parallel to the workplane.

For 3D lines, PC-DMIS filters the deviations in two planes perpendicular to each other, both planes containing the line. PC-DMIS filters these deviations in 3D.
