Interpolation mode

A specific interpolation mode can be set or forced via the interpolation compensation parameter.

• GRID (default) – linear interpolation, expects the parameter values on a grid
• SCATTER – non-linear interpolation, any distribution of parameters
• AUTO – analyses whether the parameters lie on a grid and selects GRID or SCATTER accordingly
• PATH: Error parameters are specified at the corner points of a polygon. Interpolation takes place in linear sections along the polygon.
• PATH_XY: Error parameters are specified at the corner points of a polygon in the XY plane.
