Summary of the numerical simulations performed for Sect. 3.6.

Simulation #	Driver	Height cor.	B	Ampl	τ_R	Power peak
		(Mm)	(G)	(m s⁻¹)	(s)	(s)
3.6.1	Broadband	2.0	0	10⁻³	Spiegel	183.8
3.6.2	Broadband	2.0	2500	10⁻³	Spiegel	186.0
3.6.3	Broadband	–	0	10⁻³	Spiegel	171.5
3.6.4	Broadband	–	2500	10⁻³	Spiegel	182.6

Notes. Same description as Table 1. The term “Spiegel” in the sixth column indicates that the value of the radiative cooling time in the photosphere and low chromosphere is computed using Eq. (22), while radiative losses are neglected in the rest of the domain.
