Left: averaged Stokes images (I and Q/I) at μ = 0.44 (upper panel) and 0.38 (lower panel). Right: scatter plots relating amplitudes of Q/I peak signals to continuum intensity. The Pearson correlation coefficients (r) are reported in the scatter plots. In the measurements taken at μ = 0.44, the active region is excluded for the calculation of r. Two red horizontal lines show the excluded spatial portion in the top left Stokes I and Q images. The estimated error for each point is shown in the bottom left of each plot.
