    55The routine returns a vector of observation localization weights computed according to the localization specifications in `thisobs_l` and observation coordinates in `thisobs`. The routine can be called in `prodRinvA_l_pdafomi` or `likelihood_l_pdafomi` in order to obtain the localization weights for observations. For diagonal observation error covariance matrices, the weighting is computed by OMI internally, but for nondiagonal R-matrices, the use had to implement the application of the localization.
