SuFI images coaligned to the IMaX FOV shown in Fig. 1. Panel a: SuFI 300 nm. Panel b: SuFI Ca II H. Panel c: IMaX continuum intensity (normalized to the mean quiet-Sun intensity) to which SuFI 300 nm (overlaid in red) is aligned. Panel d: IMaX line-core intensity derived from the inversions (see Sect. 2.5) and normalized to the local continuum (I₊₂₂₇), and to which calcium images (overlaid in yellow) are aligned. The yellow and red boxes are slightly misaligned due to the differential offsets in the SuFI wavelegnth channels. The gray scale is set to cover two times the rms range of each image.
