Example of radially average power spectrum for estimation of the CPD using the two-dimensional magnetic anomaly data of Block 5. Depths of 7.60 and 0.78 km are obtained as the centroid and top bound using the gradient of spectra defined as ln (P1/2/|s|) and ln (P1/2), where |s| is the wavenumber and P(s) is the radially average power spectrum.
