--> Figure 3. (a) Synthetic seismic section when the wedge model is illuminated with the zero-phase Ormsby wavelet. Green horizons are the top and base of the wedge picked by snapping to the central trough and central peak, respectively. The lateral dimension of the wedge in units of the dominant wavelength (λ) of the Ormsby wavelet is marked along the top of the section. (b) Tuning curve for bed thickness and (c) for amplitude. The tuning thickness (λ/5) is less than the Rayleigh resolution limit (λ/4). Below 5λ/8, the amplitude tuning curve is characterized by two maxima at about λ/5 (18 m) and about λ/2 (47 m).
