Once the spatial-spectral estimates have been computed, the following steps are recommended for obtaining epsilon:
- Establish the most likely wavenumber range for the inertial subrange
- Fit the spectrum of all three velocity components with the appropriate inertial subrange model
- Compute various quality indicators based on the estimated [math]\displaystyle{ \varepsilon }[/math]:
- Anisotropy
- Spectral slope of fitted spectral observations (?)
- Misfit criteria
- Propagated error from the confidence level of the spectra
