“…We applied a trial-source method to determine the direction of the gamma-ray flux [13][14][15]. This method is based on the fact that the images of Cherenkov flares from gamma rays are oriented toward the source in the focal plane of the telescope, while the major axes of the image ellipses for p showers are, to first approximation, oriented uniformly in all directions.…”

The active galactic nucleus BL Lac was observed with the GT-48 atmospheric Cherenkov detector of the Crimean Astrophysical Observatory from July 23-September 1, 1998, in order to search for ultrahighenergy gamma-ray (>1 TeV) emission. The object was in the field of view of the detector for more than 24 hours. The source was detected with a high level of confidence (7.2 σ ), with a flux equal to (2.1 ± 0.4) × 10 -11 photons cm -2 s -1 . © 2001 MAIK "Nauka/Interperiodica".
