21. This was verified for islands with an average size up to ∼1000 atoms. For these it was found that a dose of ∼1 L CO at 90 K was sufficient to achieve the saturation CO coverage.

28. The criterion used for these fits is that there are two components and that their shapes, widths, and separation are the same before and after heating for each separate cluster size.
