The curve to use for further analysis then is the middle curve of the 

 three curves for the directional spectrum. The agreement at first sight is 

 not too striking since the only points that are close are k = 11, 23j 24^, 25, 26, 

 and 27. A further study of these results will be made later. 



Ta,ble 11.5 shows the values obtained for different k by summing around 



the semicircular rings and the effect of applying the corrections due to white 



noise.
