Standard CTEQ table format

Update: 2007.04.01

The files Cteq6Pdf-2007.f and Cteq6Pdf-2007.txt replace the corresponding 2004,2006 files described below. The added PDF table files are in ctq65s.pds.zip and ctq65c.pds.zip.
This 2007 version is inclusive of all previous CTEQ6 PDF sets (read Cteq6Pdf-2007.txt), except for The CTEQ6AB series that are available from LHAPDF only.
The interface remains the same as before. The Cteq6Demo.f program remains valid.
Update: 2006.12.08

The files Cteq6Pdf-2006.f and Cteq6Pdf-2006.txt replace the corresponding 2004 files described below. The PDF table files are in ctq65m.pds.zip.
The 2006 version is inclusive of all previous CTEQ6 PDF sets (read Cteq6Pdf-2006.txt).
The interface remains the same as before. The Cteq6Demo.f program remains valid.

Update: 2004.12.14

New PDFs CTEQ6HQ (heavy quark) and CTEQ6sx (strangeness asym.) have been added. (See references in Cteq6Pdf-2004.txt.) Previous table files are still applicable. New data tables have the extension .pds. The user needs to download the cteq6.pds.zip file in order to use these new PDFs. Detailed instructions are in Cteq6Pdf-2004.txt (which is also reproduced as header lines in Cteq6Pdf-2004.f). The Demo program illustrates how the CTEQ6Pdf program is set up and called.
