The interface routines (analogue to EPS09):

21th of August 2017: A typo in the instructions given in the beginning of EPPS16.f and EPPS16.cpp files was found and corrected. The mutual order of each “-” and “+” error-set pair was reversed. For example, sets 2,3 correspond to error sets S{-1}, S{+1} and not S{+1}, S{-1} as it was stated in the earlier version.

The grid files (A=mass number) :

 The LHAPDF files:

  • The LHAPDF grids are available in the official LHAPDF website. The EPPS16 LHAPDF grids correspond to the total PDFs of the nuclei (multiplied by x) obtained from the free proton PDFs (CT14NLO) and nuclear modifications as shown below.
  • For each nucleus, the LHAPDF grids contain 97 members:

0 = central set of EPPS16 with the central set of CT14NLO

1…40   = The EPPS16 error sets multiplied (as below) by the central set of CT14NLO

41…96 = The central set of EPPS16 multiplied (as below) by the error sets of CT14NLO
