Spatial distribution of the 5 min oscillation power a) along the slit of the ground-based telescope (Si i 10827 Å and He i 10830 Å); b) along the slit in the 304 Å and HMI Fe i 6173 Å signals; c) in the 1700 Å continuum; d) in the 304 Å line; e) in the 171 Å line. Only the pixels with oscillation power exceeding 3σ² level are plotted on the distributions on the panels c)–e). The darker a point, the higher is the oscillation power in it.
