Abstract Deep inelastic scattering cross section measurements previously published by the H1 and ZEUS collaborations are combined taking into account correlations due to the systematic uncertainties. The combination is based on the complete set of HERA-I analyses. The combined data is used as the sole input for a next-to-leading order QCD parton distribution function fit. The resulting HERAPDFs have reduced uncertainties compared to separate analyses of the H1 and ZEUS experiments.
