Example amplitude spectrum from the Gorda Rise crest sampled 

 at azimuth 115 degrees. The straight line segment through 

 the spectrum represents the model prediction, rather than a 

 least squares fitted line. As seen in Figure 6-6, this 

 particular azimuth represents a large deviation of the 

 fitted parameters from the model sinusoid. The model line 

 still appears to fall well within estimation noise, even for 

 this "worst case" example.
