The first row (A1), (A2) displays the high-contrast features of the AR dataset. The second row (B1), (B2) shows the low-contrast, fine-scale structures of the QS dataset. Panels (A1) and (B1) are the TiO photospheric signals, and Panels (A2) and (B2) are the observed He I 10830 Å signals. All images have a spatial size of 400 × 400 pixels.
