PDF Sets: NNPDF2.3 with QED correctionsHere we present the procedure to install the NNPDF2.3 grids with QED corrections in LHAPDF 5.9.0.The tutorial proposes a code example in C++ and FORTRAN languages, using the LHAPDF interface.

Basic instructions to obtain the photon PDF from LHAPDFIn C++: LHAPDF::hasPhoton(); // returns true if the photon PDF is availableLHAPDF::xfxphoton(x,Q,f); // with f=-6,7. It returns the x*photon PDF if f=7. In Fortran: has_photon() # returns true if the photon PDF is available evolvePDFphoton(x,Q,f,xphoton) # with f=-6,6. The x*photon PDF is stored in xphoton.
