Locating TeV Gamma-Ray Sources with Sub-Arcminute Precision: the Pointing Calibration of the HEGRA System of Imaging Atmospheric Cherenkov Telescopes
TL;DR: In this paper, the HEGRA IACT system was used to reconstruct the origin of individual primary particles with an accuracy of 0.1 degree or better, using bright stars distributed over the sky as references.
