Grid files

Here we provide pre-optimized grid files for various processes implemented in VBFNLO. The settings of parameters and cuts, which have been used to obtain these files, are identical to those found in the regress subdirectory of the release. The VBFNLO version used is indicated below.

The optimal grid depends both on the cuts and on the parametrization of the phase space, which can change between different VBFNLO versions. Using the grids with different cuts or another program version may result in wrong cross sections and distributions and in larger errors.

Usage

Unpack the appropriate tar-file in the folder where you are going to run VBFNLO:

tar -xf <filename>

For convenience we also provide a tar-ball containing all grid files. The directory names correspond to the names in the regress subdirectory of the distribution.
