Statistical Analysis: Statistical Contouring
A Contour Plot is the main tool in Dips for analyzing mean and / or maximum pole concentrations. It is used to visualize the clustering of orientation data not immediately evident from a Pole Plot or a Scatter Plot. The contours represent statistical pole concentrations, calculated using the distribution method (Fisher or Schmidt) specified in the Stereonet Options dialog.

Statistical Analysis: User Defined Set Windows for Joint Sets
Add Set Window allows the user to draw windows around data clusters on the stereonet, for the purpose of obtaining mean orientations of data (poles) within the windows. The mean orientations can be plotted as poles and/or planes on the stereonet, and set statistics (confidence and variability cones) can be plotted (Edit Sets option) or listed (Info Viewer option).
Add Set Window option under Sets menu
