Alternative `Summary' method for class "Sncf2D".
cc.offset(object, xmax)an object of class "Sncf2D", usually, as a
result of a call to Sncf2D or spline.correlog.2D.
The maximum distance to consider (default is no upper limit).
An matrix of class "cc.offset" is returned with columns:
the cardinal angle (in degrees).
the distances (in the positive direction) to the mode of the (cross-) correlation function (with 95% confidence bounds).
the correlation at the mode (with CI) for each of the cardinal angles.
