Comparison of HAWC's Eye data and Monte Carlo simulations — •Mark Meyers for the HAWC's Eye collaboration — Physics Institute III A, RWTH Aachen, Germany

HAWC's Eye is an array of Imaging Air-Cherenkov Telescopes which runs in coincidence with the High altitude water cherenkov observatory (HAWC), forming the first hybrid detector for cherenkov light, observing high energetic gamma rays and cosmic rays in the range of 100 GeV to 100 TeV. The goal is to enhance the performance, by improving the energy calibration and arrival direction reconstruction. In a Monte Carlo simulation, extensive air showers of protons and gammas are observed by an array of 55 telescopes. Properties of the produced detector images in the single telescopes are compared to those that have been produced in measurements, to verify the simulation. These measurements were obtained in stereo observations with two telescopes in three campaigns during the years 2019 and 2020. Potential ways to improve the simulation according to the obtained results will be investigated.
