12. Recent experiments show that the decoration of the steps with iron clusters is not necessary. Monolayer films of good quality may be prepared on a clean Ag(111) surface as described above by adsorption of more than one monolayer and by subsequent desorption of the excess molecules.
13. The absolute error of about 5% for x-and y-calibration is rather large, i.e. this leads to an error of 10% for the measurements of an area. However, the relative uncertainty when looking at the ratio between different lengths (or areas) is much smaller, and is estimated to be about 1% (2%).
14. The experimental uncertainty for the angle between is estimated to be about 3°.
15. The relative size of the unit cells may be best concluded if the different structures are contained in a single large-area scanframe, which has been observed in quite a few images. One may then compare the area of a large number of molecules (e.g. 100) for the different superstructures. It clearly reveals that the size of unit cell III is smaller than II, which again is smaller than I.
