Alternative summary method for class "Sncf2D".
cc.offset(object, xmax = NULL)an object of class "Sncf2D", usually, as a result of a call to Sncf2D or spline.correlog2D.
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.
