Relative contributions of shocks (purple), CSs (green), and non-steep gradients (white) to the mechanical heating of the chromosphere (Q_mech = Q_ν + Q_η + Q_comp, in red, blue, and grey, respectively). The profiles used in the right panel of Fig. 9 are spatially averaged over the chromospheric extent (0.6 ≤ z ≤ 2.57 Mm), with the outer ring indicating the physical processes involved (shocks, CSs, or neither), and the inner ring explicitly showing the associated dissipation mechanisms: viscous (red), ohmic (blue), and compression (grey). A darker shade of grey is used to highlight the shock compression contribution (see also Appendix A). The hatched segments indicate the contribution of regions where both shocks and CSs overlap.
