Summary

Story summary

Six plane-subtracted STM topographs show transitions in laser illumination directions Q1, Q2, and Q3.
Fourier transforms reveal charge density wave peaks and Bragg peaks, with changes in tip shape and impurity distribution across scans.
CDW intensity and Bragg lengths vary with illumination direction, creating significant differences in topographs taken under identical conditions.
