Comparison between experimental measurements and numerical results for the DSSF. Rescaled experimental data at fixed frequency are shown for (A) $\omega =0.75$ meV and (B) $\omega =6$ meV [data from ref. 10]. Theoretical results for the DSSF of KAFM with nearest neighbor couplings ($J_2=J_3=0$) at fixed frequency are plotted for (C) $\omega =0.2J_1$ and (D) $\omega =0.6J_1$ (related to the dashed line cut in Fig. 2C). The extended BZ is indicated by the white dashed lines.
