Ca II H plus Hε spectral profiles for different solar structures indicated with crosses in Fig. 1. Solid lines: observations taken with the CHROMIS instrument. Dashed lines: degraded synthetic spectra. The Hε emission profiles are shown in orange and light blue. Orange synthetic profile (1.5D HNEI) is taken from Fig. 6 at x ≈ 13.6 Mm and y ≈ 17.7 Mm (red contours). Light blue synthetic profile (1.5D HNEI) shows the same as the one in the bottom right panel of Fig. 12. The red spectral profile is taken from a magnetic bright point. The synthetic profile (3D SE) is shown in the bottom left panel of Fig. 10. The turquoise spectral profile is taken from a dark fibrilar structure. The synthetic profile (1.5D HNEI) is shown in the bottom right panel of Fig. 10.
