a XRTS measurement by Glenzer et al.34 (green), theoretical Mermin model (also taken from Ref. 34) giving Tmodel = 12 ± 2 eV (red), SIF R(E) (blue), and averaged tail for E ≥ 40 eV (black); b convergence of our model-free temperature diagnosis with respect to the integration boundary x of \({{{{{{{\mathcal{L}}}}}}}}\left[S({{{{{{{\bf{q}}}}}}}},\, E)\right]\) with (blue) and without (green) correcting for the instrument function. The dashed line depicts the nominal value of Tmodel and has been included as a reference. The shaded areas depict the respective uncertainty range; c corresponding results for the imaginary-time intermediate scattering function F(q, τ), with the vertical lines indicating the position of the minimum.
