Upper-left panel: linear polarization image in the FeI 630.25 nm line at the southern solar limb. Upper-right panel: linear polarization images in the FeI 630.25 nm line at solar disk center. Lower-left panel: unsigned circular polarization image in the FeI 630.25 nm line at the southern solar limb. Lower-right panel: unsigned circular polarization images in the FeI 630.25 nm line at solar disk center. The colors are coded according to the logarithm of the polarization normalized by its mean value over the image. For the linear polarization, at the limb Max/Mean = 16.00 and Min/Mean = 0.56; at disk center, Max/Mean = 10.05 and Min/Mean = 0.52. For the unsigned circular polarization, at the limb Max/Mean = 23.14 and Min/Mean = 0.26; at disk center Max/Mean = 35.75 and Min/Mean = 0.23. Color code: same as in Fig. 1.
