SPECTRE
***************************************************************************** 

After running the model, you can compute spectra with the program :program:`SPECTRE`, that gives the kinetic energy density according to the wavelength or the wave number :cite:p:`ricard_kinetic_2013`. The calculation uses a discrete cosinus transform to convert grid-point fields into spectral space ones.
