EPS09 Parametrization of nuclear modifications to PDFs

 

Interface for calculating scale dependent nuclear ratios based on article

The interface routine:

The Fortran code for the parametrization: eps09.f

The C++ code for the parametrization and a test program with a Makefile to compile and link these: eps09_cxx.tgz (Thanks to Thomas Ullrich!)
