Scientific paper

Gamma-ray experiments using the imaging atmospheric Cherenkov technique have an angular resolution of typically better than 0.1° per event in stereoscopic mode. The centroid of a point-source emitter, however, can be determined with higher precision, down to a few arcseconds for strong sources. This is of special interest when an excess could be due to several potential sources in the field of view. Here it is shown that H.E.S.S. achieves a pointing precision of 10 to 20 arcseconds by means of a mechanical pointing model. This is demonstrated by reconstructing the position of the AGN PKS 2155-304, which is a point source emitter with a priori known position. The high precision allows to show that the TeV signal from the galactic centre region is consistent with the position of the galactic centre Sgr A*.
