17. In the case of SR steps there should be an additional term in (1) that accounts for interaction of the monopoles due to the discontinuity of surface stress at the step-edge. We have ignored this term in our analysis of vicinal surfaces with θ>3° since the magnitude of this term becomes significant for small vicinal angles (θ<1°).

20. From the STM images of the stepped mounds in Ref. 4 we have inferred that the [110] oriented steps are of the double-height type.
