An additional error will be introduced by the multi-dimensional interpolation scheme from
the LUT table. The error is not provided yet in the draft ATBD but will be given later.
Note that no error budget can be estimated for the third and fourth Stokes parameters as no
data as function of wind speed are currently available for validation.
