Fig. A.1

Full disk images of B_r (upper row), B_θ (middle) and B_φ (low row). First and third columns show the vector field components in image coordinate system, while second and fourth columns are in the heliographic coordinate system. Three examples are marked by arrows of different color. Setting α to unity emphasizes pixels, which otherwise are below the noise threshold.
