Abstract
The direct correlation function for a fluctuating interface in a two-dimensional solid-on-solid lattice model is studied. They obtain for a weak gravitational field an asymptotic expression for the direct correlation function that agrees well with previous numerical results. In particular two different vertical length scales appear.Keywords
