Maps of Stokes parameters for the Sii 10 827.1 Å  line and the Hei triplet at 10 830 Å. Panel a) shows the continuum intensity, I_c, at 10 833 Å. Panels b)−d) corresponds to Stokes Q/I_c, U/I_c, and V/I_c maps of the Sii  line, respectively. The line depression of the blended red components of the Hei triplet, (I_c−I_He) /I_c, is displayed in panel e). Stokes Q/I_c, U/I_c, and V/I_c maps for the Hei triplet are presented in panels e)−g), respectively. The lower and upper limits of the Stokes Q/I_c, U/I_c, and V/I_c maps are indicated in the lower part of the respective image. The Stokes maps presented here are an average over a range 0.27 Å  wide centered on λ−λ₀ = −3.10 Å  and λ−λ₀ = −0.35 Å  for the Sii  line and Hei triplet, respectively, with λ₀ = 10 830 Å. The Stokes V/I_c profiles along the red line marked in panel d) are plotted in Fig. 2. The lower part of the line is directed toward the closest part of the solar limb. Three arcs in panel a) show the locations of various parameters that are depicted in Fig. 6.
