✦ Synopsis

A precise knowledge of the angular resolution of scintillator arrays used to observe extended air showers (EAS) is of key importance in the search for VHE/UHE (\gamma) point sources. Four independent methods have been used to determine the mean resolution for which a value of (\left\langle\Delta \Theta_{63}\right\rangle) of (0.8^{\circ}\left(1.0^{\circ}\right)) at a proton threshold of (50(40) \mathrm{TeV}) has been found for the HEGRA EAS-array.
