== Dissipation rate estimation ==

#       Extract the profile defined in step 2. 
#       High-pass filter the shear-probe and (optionally) the vibration data.  
#       Identify each diss-length segment in the profile. 
#       De-spike the shear-probe data, and track the fraction of data affected by de-spiking within each diss-length segment. This will become a quality-control metric. 
#       Calculate the frequency spectra and cross-spectra of shear and vibrations for each diss-length segment using the method described here. 
#       Extract the original and the vibration-coherent clean shear-probe frequency spectra. 
#       Correct shear and vibration frequency spectra for the high-pass filter. 
#       Correct the cleaned frequency spectra for the bias induced by the Goodman algorithm. 
#       Convert the frequency spectra into wavenumber spectra using the mean speed for each diss-length segment.
#       Correct the spectra of shear for the wavenumber response of the shear probe. 
#       Apply an iterative spectral integration algorithm to estimate the variance of shear, which is described here. 
#       Calculate the rate of dissipation by multiplying the shear variance by
