Figure 14 The left panel is the residual without using a whitening filter. The right panel is the residual using a whitening filter. Note how the residual is showing only minimal structure.
We can now use our multiple realization machinery to produce multiple interval velocity models that have approximately the correct covariance. The right panel of Figure shows 80 interval velocity realizations. The left panel shows those realizations converted back to . Note how the functions stay within variance bounds. In addition, as we expected, we see larger variance where our bounds are wider. If we look at the mean and variance of our interval and rms (Figure ) estimates we get another interesting result. Areas of large variance are not always correlated.
Figure 16 The left panel shows the mean of the (solid line) and (dashed line) of 80 realizations overlaying the stack power. The right panel shows the variance of and for the 80 realizations.
