for each wave envelope. The number of envelopes to he plotted is punched 

 right-justified in columns 1 to 5 of another card and placed at the front 

 of the data check. 



The plots generated by WVHTC2 give wave height deviation from the 

 local mean with the best fit sine curve superposed. 



5. Determining K^. 



K^ is determined from the plot by dividing the amplitude of the sine 

 curve by '^/[VG- Both values are written in the plot heading.
