a Diffraction pattern measured at 125 K (LT phase) without photoexcitation. Color circles show the positions of the selected Bragg peaks. b Difference between the diffraction patterns of the 125 K (LT) and 300 K (HT). c Photoinduced signal measured after 5-ps time-delay at 125 K. d Photoinduced signal measured after 100-ps time-delay at 125 K. Insets of a–d show the selected area of the diffraction pattern indicated by the yellow rectangle in a. The black circles in the insets are the positions of the several selected Bragg peaks. e Kinetic traces of selected Bragg peaks’ intensity. Short-time relative change in the intensity of selected Bragg peaks from −0.5 to 9 ps, and long-time relative changes in the intensity from +10 to 150 ps. The solid lines show the results of the global fitting (Supplementary Equation 1). Source data are provided as a Source Data file.
