/** \class SinclairToReciprocalCircularCovarianceMatrixFunctor
* \brief Construct the fully reciprocal polarimetric circular covariance matrix
* with Sinclair matrix information.
*
* Output value are:
* - channel #0 : \f$ S_{ll}.S_{ll}^{*} \f$
* - channel #1 : \f$ S_{ll}.S_{lr}^{*} \f$
* - channel #2 : \f$ S_{ll}.S_{rr}^{*} \f$
* - channel #3 : \f$ S_{lr}.S_{lr}^{*} \f$
* - channel #4 : \f$ S_{lr}.S_{rr}^{*} \f$
* - channel #5 : \f$ S_{rr}.S_{rr}^{*} \f$
*
* This is a adaptation of the SinclairToCircularCovarianceMatrixFunctor, 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.
