Fig. 5
Center-to-limb variation of linear polarization. Different kind of lines depict our calculations for different model atmospheres: FALC, FALP, FALA, HSRA, and LTE5800-45 (Phoenix model for Teff = 5800 K and log g = 4.5). The thick dashed line (F&S99, FALC) corresponds to the analytical function for the FALC model taken from Fluri & Stenflo (1999), while the thick dotted line (S05, FALC) represents the analytical function taken from Stenflo (2005).
