Erratum: ``Surveys for z > 3 Damped Lyα Absorption Systems: The Evolution of Neutral Gas'' (ApJ, 543, 552 [2000])

There is a typographical error in equation (7). The analysis in the paper was performed using the correct version, which follows:dX/dz=(1+z)²[(1+z)²(1+Ω_Mz)-z(z+2)Ω_Λ]^1/2.(7)Thanks to Len Cowie and Eric Gawiser for pointing out this error.
