10. This formula differs from our previously published result by a factor of (1 - θ) in the first term. This factor arises from the restriction that any given site cannot be occupied by more than one adsorbate. This factor was introduced by B. N. J. Persson et al. (see Ref. 10).

13. The lines in Fig. 2 do not go exactly to zero at ω = 0 due to the approximation of the integral I(ω) by a finite sum.
