FIG. 7.14 Determination of operator length and prediction lag parameters on a schematic autocorrelation trace with reflec-
tion energy of two multiples (M 1 and M 2 ). Optimum deconvolution parameters (α and nΔt) are shown only for the first-order
multiple M 1 .

FIG. 7.15 Predictive deconvolution outputs of a shot gather (top) and its autocorrelograms (bottom) with different operator
lengths for a constant prediction lag of α ¼ 40 ms.
