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, Ic, at 10 833 Å. Panels b)d) corresponds to Stokes Q/Ic, U/Ic, and V/Ic maps of the Sii  line, respectively. The line depression of the blended red components of the Hei triplet, (IcIHe) /Ic, is displayed in panel e). Stokes Q/Ic, U/Ic, and V/Ic maps for the Hei triplet are presented in panels e)g), respectively. The lower and upper limits of the Stokes Q/Ic, U/Ic, and V/Ic 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 λλ0 = −3.10 Å  and λλ0 = −0.35 Å  for the Sii  line and Hei triplet, respectively, with λ0 = 10 830 Å. The Stokes V/Ic 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.
