Time–distance plots of the scaled velocities for the perturbations parallel, perpendicular, and azimuthal to magnetic flux surfaces, a proxy for the slow magnetoacoustic mode (left), fast magnetoacoustic mode (middle) and Alfvén mode (right), respectively. All plots are for the case of a localised inclined driver of 15° (WD1) for an azimuthal slice φ = 46.1° at three different radial cuts of (a) r = 1.5 Mm, (b) r = 3.78 Mm and (c) r = 7.97 Mm. The β = 1, fast mode reflection (z_refl) and transition region layers are shown by the green, black dashed and grey contours, respectively. For the purpose of this illustration, the fast mode reflection height was calculated using a horizontal wavenumber k_⊥ = 4.0 Mm⁻¹. Note the different colour bar used for the , and components in all panels.
