Line cut (blue line) of the FFT of \(g({\bf{r}},E=20\,{\rm{meV}})\) map in Fig. 5h along the Cu–O bond direction exhibits a peak at \({q}_{{\rm{CO}}}=0.25\,(2{\rm{\pi }}/{a}_{0})\) that is associated with the charge-ordered state. The magenta line is a Gaussian fit to the peak plus a decaying exponential background. The full-width at half-maximum of the peak yields a correlation length of about 14a0.
