* − Parameters A (activity) and B (background) and their uncertainties have been estimated in the LSF fit together with all the other DN parameters. All these data included in the correlation matrix (see Appendix A for detailed discussion on the a1 and da1. Full matrix is presented there). However we did not included all correlation coefficients in the final matrix because these data are related to specific experiments and is not really needed for implementation of DN parameters. But they are certainly obtained with taking into account parameters A and B.
