22. An adsorbate located in a hollow site on graphite would not give rise to an electron scattering pattern because the scattered waves emanating from each nearest B-site atom would differ in phase by 2π/3 and would sum to zero (2).

24. In filtering all experimental images we used a low-pass filter and all images were acquired in an ambient atmosphere.
