##HERAFitter is a set of PDF fitting tools initialy developed jointly by the H1 and ZEUS collaborations for determination of the parton density functions and currently extended to LHC experiments and theory groups. Independent developers are also ##encouraged to add their contribution to the package. The HERAFitter codes were used to obtain the HERAPDF sets.
