Fig. 19
201 × 201 pixel inset, centred on disc centre, of the 720 s continuum intensity image, with the points displaying |⟨Bl⟩| > 3σ⟨Bl⟩ in the 720 s longitudinal magnetogram highlighted. Blue corresponds to the points realizing this condition in both the uncorrected and restored magnetogram, red the points fulfilling it only in the uncorrected data and green the points satisfying it only in the restored data. The grey scale is saturated at 0.8 and 1.2 times the mean quiet-Sun level.
