ResBos input grids for the Tevatron Run-2

Input grids for W and Z boson production in the Tevatron Run-2 
in the presence of non-trivial rapidity dependence in the resummed 
transverse momentum distributions.

The input grids are computed using the resummation program Legacy, described
in F. Landry et al., Phys.Rev. D67, 073016 (2003). They are computed using
the nonperturbative Sudakov function (BLNY) obtained in  
F. Landry et al., Phys.Rev. D67, 073016 (2003), 
or the nonperturbative Sudakov function with rapidity-dependent q_T
broadening effects obtained in S. Berge et al., Phys.Rev.D72:033015 (2005). 
They also use the CTEQ6M PDF set, published in J. Pumplin et al., 
JHEP 0207:012 (2002). Please acknowledge these papers in your publication.
