Near the directed percolation threshold, pd, the wetting velocity upsilon scales as (1- upsilon ) approximately (pd-p)theta . The authors extrapolate from calculations on strips of finite width to show that, on the two-dimensional square lattice theta =1.73+or-0.02. This agrees with a scaling argument by Barma and Ray (Phys. Rev. B., vol.34, p.3403, 1986) which predicts theta = nu /sub ///.
