Measurements of open charm production cross sections in deep-inelastic ep scattering at HERAfrom the H1 and ZEUS Collaborations are combined. Reduced cross sectionssigma_red^cc for charm production are obtained in the kinematic range of photon virtuality 2.5<Q2<2000 GeV2 and Bjorken scaling variable 0.00003<x<0.05. The combination method accounts for the correlationsof the systematic uncertainties among the different data sets. The combined charm data togetherwith the combined inclusive deep-inelastic scattering cross sections from HERA are used as input for a detailed NLO QCD analysis to study the influence of different heavy flavour schemes onthe parton distribution functions. The optimal values of the charm mass as a parameter in these ...
