/** \class SinclairToReciprocalCovarianceMatrixFunctor
* \brief Construct the reciprocal fully polarimetric covariance matrix
* with Sinclair matrix information.
*
* Output value are:
* - channel #0 : \f$ S_{hh}.S_{hh}^{*} \f$
* - channel #1 : \f$ \sqrt{2}.S_{hh}.S_{hv}^{*} \f$
* - channel #2 : \f$ S_{hh}.S_{vv}^{*} \f$
* - channel #3 : \f$ 2.S_{hv}.S_{hv}^{*} \f$
* - channel #4 : \f$ \sqrt{2}.S_{hv}.S_{vv}^{*} \f$
* - channel #5 : \f$ S_{vv}.S_{vv}^{*} \f$
*
* This is a adaptation of the SinclairToCovarianceMatrixFunctor, where \f$ S_{hv}=S_{vh} \f$.
*
* The output pixel has 6 channels : the diagonal and the upper element of the reciprocal matrix.
* Element are stored from left to right, line by line.
