Query: Analysis optimisation for more than 10 TeV gamma-ray astronomy with
  IACTs   The High Energy Stereoscopic System (H.E.S.S.) is one of the currently
operating Imaging Atmospheric Cherenkov Telescopes. H.E.S.S. operates in the
broad energy range from a few tens of GeV to more than 50 TeV reaching its best
sensitivity around 1 TeV. In this contribution, we present an analysis
technique, which is optimised for the detection at the highest energies
accessible to H.E.S.S. and aimed to improve the sensitivity above 10 TeV. It
includes the employment of improved event direction reconstruction and
gamma-hadron separation. For the first time, also extensive air showers with
event offsets up to 4.5$^{\circ}$ from the camera centre are considered in the
analysis, thereby increasing the effective Field-of-View of H.E.S.S. from
5$^{\circ}$ to 9$^{\circ}$. Key performance parameters of the new high-energy
analysis are presented and its applicability demonstrated for representative
hard-spectrum sources in the Milky Way.
