Left: normalized vertical magnetic field B_z/B_eq at the end of the kin interval (top) and at the beginning of the sat interval (bottom), as defined in the text. Right: variation of different f-mode characteristics with ﹩{\tilde{k}}_{x}﹩ for different runs. (a) Mode strength (μ_f), (b) relative frequency shift, and (c) full width at half-maximum (FWHM) of the f-mode, all as functions of ﹩{\tilde{k}}_{x}﹩. Tick marks at the top indicate the corresponding spherical harmonic degree ℓ.
