Time evolution of contribution functions and plasma temperature for a column in the quiet Sun at location A (Fig. 1), with the shock-wave event studied in detail in Eklund et al. (2021a). The contribution function of band 3 (a) and band 6 (b) with heights of 0.25 and 0.80 times the contribution function integrated from the top is marked by the dashed and solid lines, respectively. (c) Plasma temperature with each of the representative heights of the two components of bands 3 and 6 marked for reference. The ticks t_ex and t₁ – t₃ mark the times for the in-depth discussion in connection to Figs. 4 and 7.
