Panels A–C: continuum intensity, CP maps, and LOS filtered velocity map from Fe I line measurements. Panels D–G: line core intensity, line blue wing, CP maps, and LOS velocity maps from Ca II line measurements. Down–flow and up–flow correspond to positive and negative velocities, respectively. A Gaussian filter is applied to the chromospheric CP maps (panel F). The dashed horizontal lines indicate the slices where the time slice is computed (see Sect. 2 for more details). A movie of the data presented in this figure is available online.
