Comparison of total polarization with reversed granulation images. Upper-left panel: cross-correlation of FeI 630.15 nm polarization image with the reversed granulation at μ = 0.66 (sinθ = 0.75) in the northern hemisphere. Upper-right panel: cross-correlation of FeI 630.15 nm polarization image with the reversed granulation at μ = 0.66 in the southern hemisphere. Lower-left panel: north-south cut along the polar axis of the 2D cross-correlation shown in the upper-left panel. Lower-right panel: north-south cut along the polar axis of the 2D cross-correlation shown in the upper-right panel.
