  1. The two independent results correspond to the fitting of (i) the neutron-integrated magnetic intensities collected in D10 (unpolarized neutrons) and (ii) the fitting of the neutron polarization matrices (SNP) measured in D3. The spherical neutron polarization matrices are more sensitive than the integrated intensities to the orientation of the spins in the ab plane. The refined domain population is also shown.
