CTEQ6 parton distribution functions


The CTEQ6 family of PDFs is superseded by newer, more complete, CT10 PDF sets.

CTEQ6 parton distribution functions are publicly available as a part of the LHAPDF Fortran library
Here you can download a standalone Fortran interface and demonstration program, as well as the tables with interpolated PDF values for the latest general-purpose set (CTEQ6.6M and 44 eigenvector sets for computation of PDF uncertainties) and other CTEQ6.XX sets. 
An alternative interface for simultaneous interpolation of several CTEQ PDF tables has been developed by Zoltan Nagy. It is written in C and can be linked to C/C++/Fortran modules using gcc and other compilers.
