Fig. 2: Energy scans of the soft phonon mode in 2H-TaSe2.

Energy scans taken at q || [100] at a–c T = 250 K and d–f 130 K. Dashed (red) lines are fits consisting of DHO functions convoluted with the experimental resolution (blue solid lines), estimated background (straight dotted line) and a resolution limited pseudo-Voigt function for the elastic line (black dash-dotted line). Error bars represent standard deviations. Error bars represent s.d.
