To display the MRS constituents In detail, the constituent amplitudes for 

 each record were squared to be representative of wave energy. They were then 

 normalized by the total of all squared amplitudes in the record and plotted as 

 a function of frequency (Figs. 16 to 29). The band spectrum, computed with 

 cosine bell data window which best matches the times for MRS analysis, is also 

 shown in each figure. The band spectrum is formed by combining variance from 

 a fixed number of adjacent analysis frequencies.
