WellCAD Basics - Advanced Logic Technology

A - standard step function (None)
B - inverse area smoothing (Area)
C - inverse area squared (Inverse Area)
D – exponential smoothing (Exponential)
The degree of smoothing increases from A to D.
APPENDIX A - 461
Signif. Sigma: Number of standard deviations defining the expected count for a
uniform distribution. Selecting a lower value (default and max is 3) gives a smaller
counting element, more localized density estimates and less smoothing. E.g. for large
scattering of data a value of 3 might be appropriate while the value can be reduced if
the data tends to build a point maximum.
Min. Contour: The initial contouring interval.
Contour Interval: Step of the contour line intervals.
