The same input parameters mb(SF) and mupi used for the fit to all the independent analyses are used. In this case we just look at mx analyses.

where the errors correspond to the statistics, the experimental systematics, the modeling of b -> c l nu and b -> u l nu decays, the HQE parameters mb and mupi2, the functional form of the SF, the subleading shape functions, the variation of the matching scales, and the Weak Annihilation. No uncertainty is assigned for possible duality violations.
