Comparison of photospheric and chromospheric components. The first row shows the AR; the second row shows the quiet region. Columns (1)–(2) display the original TiO and He I 10830 Å observations; columns (3)–(4) present the generated photospheric reference and extracted chromospheric absorption maps. All images have a spatial size of 400 × 400 pixels. Animations of the aligned sequences are available online for the AR (300 × 300 pixel, 3 s) and QS (400 × 400 pixel, 4 s) regions. These animations cover ∼40–45 minutes of solar evolution, highlighting the dynamic chromospheric fibrils (column (4)) isolated from the composite signals (column (2)).
