Abstract

We evaluated the differential sensitivity of the 5 atmospheric Cherenkov telescopes under construction as part of the TAIGA astrophysical complex. The procedure of simulating of detected gamma-rays with energies from 2 to 200 TeV in the stereo observing mode is described, as well as the gamma-hadron separation technique used to determine the differential sensitivity of the facility.

Keywords
