IXS spectra at a (0, 0, 6) + qs and b (0, 0, 6) + q*, measured at various temperatures. The solids lines are fits to a DHO and an elastic peak, convolved with the instrumental resolution. From these fits, c E0 and d γ are extracted and compared between the two wavevectors. The 95 K and 100 K scans in (a) are resolution-limited. The 95 K, 100 K, and 105 K data in (b) contain an inelastic response but cannot be reliably distinguished from the elastic peak. DHO fit parameters are not shown for these scans. IXS spectra at e (2, 2, 0) + qs and f (2, 2, 0) + q*, compared between 85 K and 100 K. The solids lines are fits to DHOs and an elastic peak, convolved with the instrumental resolution. The error bars in (a), (b), (e) and (f) represent statistical errors of 1 s.d., and the error bars in (c) and (d) are least-square fit errors of 1 s.d.
