Resummed grids for extreme variations of the nonperturbative
Sudakov function allowed by the global q_T fit; these grids
can be used to evaluate uncertainties in the resummed cross
section due to the nonperturbative contributions using the
Hessian matrix method

For individual grids: 
      c221 -- CSS piece with A,B,C functions evaluated up to orders 2,2, and 1
      or y -- Y piece evaluated up to NLO


The input grids are computed using the resummation program Legacy, described
in F. Landry et al., Phys.Rev. D67, 073016 (2003).
The nonperturbative functions S_NP(b,Q) are described in A.Konychev, P. Nadolsky,
Phys. Lett. B633, 710 (2006). The procedure to calculate the uncertainty due
to S_NP(b,Q) and values of parameters are described in snp_fit.pdf. The grid ID's 
correspond to the extreme parameters vector as follows:

 Extreme
parameter    Grid ID
  vector
  a_(1)^+      01
  a_(1)^-      02
  a_(2)^+      03
  a_(2)^-      04
  a_(3)^+      05
  a_(3)^-      06

For 3sigma errors, replace 01->31,..., 06->36.
