ASAR/ERS - wave mode comparative spectra (cross spectra).
![[Cross Product]](cross-prod.gif)
Left: half of ASAR cross spectra real part (symmetric and equivalent to half ERS
spectra).
Right: half of ASAR cross spectra imaginary part (antisymmetric and gives propagation
direction)
ERS spectra: real part only (propagation direction is ambiguous)
0 255
Nota: the wave length convention is reversed.
