Scatter plots of V₆₃₀₂ vs. V₆₃₀₁ for the Hinode deep mode data set. The top panel shows the plot for all pixels at the original Hinode resolution (same as Fig. 8 of Stenflo 2010), while the bottom panel shows what happens after the same data set has been spatially smoothed with a window of area 1 Mm². If the magnetic fields were intrinsically weak (less than a few hundred G), the points would fall along the dashed line.
