Fig. 8
Center-to-limb variation of polarization at 4506 Å for different solar model atmospheres, which are depicted by different line types and labeled on the plot. The stars with error bars depict the measurements obtained by Wiehr & Bianda (2003). The Phoenix model has parameters that are the closest to the solar one, such as Teff = 5800 K and log g = 4.5.
