  We present a list of optimized damping range parameters $s_R$ to be used with
the Tkatchenko-Scheffler van der Waals dispersion-correction scheme [Phys. Rev.
Lett. 102, 073005 (2009)]. The optimal $s_R$ are obtained for seven popular
generalized-gradient approximation exchange-correlation density functionals:
PBE, RPBE, revPBE, PBEsol, BLYP, AM05 and PW91. The optimization is carried out
in the standard way by minimizing the mean absolute error of the S22 test set,
where the reference interaction energies are taken from coupled-cluster
calculations. With the optimized range parameters, we assess the impact of van
der Waals corrections on the ability of these functionals to accurately
describe structural and thermodynamic properties of liquid water: radial
distribution functions, self-diffusion coefficients and standard molar
entropies.
