We study the local variations of η0 and ξ (Milne-Eddington model) which are necessary in order to bring in agreement three independent determinations of the total field H, obtained from simultaneous observations of the two lines λ 5250,2 Fe I and λ 5225,5 Fe I. The distribution of the broadening as a function of field direction is consistent with the motions induced by hydromagnetic waves.
