Estimating horizontal scale of fluctuation with limited CPT soundings

The paper explores the possibility of estimating the horizontal scale of fluctuation (delta(h)) with limited CPTs. The following conditions are desirable: (1) the CPT depth is large; (2) there are more than two CPTs; (3) the CPT separation distances are distinct and preferably less than 2 x delta(h); and (4) the Whittle-Matern auto-correlation model is adopted.
