a, b Images of CDW diffraction signal taken at 45 K without (a) and with (b) the 10 \(\mu\)m pinhole (see text). Due to the much lower count rate in b, the image is obtained from an average of three frames, each with 10 s of exposure time. c–f Waterfall plots (see text) of the time series of diffraction intensities extracted from a horizontal strip taken near the dashed line in b. Global intensity variations over time (Supplementary Fig. 7) have been compensated by normalizing the mean intensity of each time frame. g Autocorrelation of speckle patterns at different temperatures. The inset shows fitted values of the coherence time \({\tau }_{0}\) (see text) that characterizes the rate of domain motion. Error bars in the inset represent uncertainties (1 s.d.) obtained from least-square fitting of the data. The autocorrelation at 62 K may exhibit some initial rapid decay (Supplementary Fig. 8) that is not accounted for by the fit.
