Observations: power spectra of the vertical component of kinetic (top panel) and magnetic energy (middle panel) and power spectra of the total magnetic energy (bottom panel). Green lines indciate the results of 2D inversions at different heights (log τ = 0 solid and −2.0 dashed). Black lines represent spectra of the corresponding parameters obtained from Solarsoft routines (see the text). Purple lines indicate the curves obtained from Sim 2 (purple curves in Fig. 2).
