Temperature and structure measurements of heavy-ion-heated diamond using in situ X-ray diagnostics

Fig. 3. Posterior predictions modeling the spectrally resolved XRTS signal (black) as the sum of an elastic (orange) and inelastic (yellow) contribution. The latter two curves were obtained by simulating the experiment using our ray tracing code with input from DFT-MD in the case of the incoherent curve. The full model (blue) additionally assumed a Gaussian noise with constant unknown magnitude. To guide the eye, smoothed curves of the noisy data and full predictions are plotted as solid lines.
