a, Typical FT of the Sb surface. The 2 × 2 CDW peaks along the three directions are labelled Q1 to Q3. b-c, Zoomed in FT images showing that the intensities of Q1 and Q3 are mostly localized to a single pixel. d, Light-induced switching of the CDW intensity with an arbitrary illumination sequence with laser polarization along either \({{\boldsymbol{E}}}_{1}\) or \({{\boldsymbol{E}}}_{3}\) (same as Fig. 3a), with the CDW intensities determined by the single pixel method. e, CDW intensity contrast along the same arbitrary illumination sequence with the nearest averaging methods (5 pixels in total). The trends in the intensity contrast remain the same while the absolute value of the intensity contrast is suppressed in most cases suggesting that using the single pixel method provides better signal.
