TITLE: Validation of Simulation Data for the IceAct Telescopes

ABSTRACT: IceAct is a surface array of Imaging Air-Cherenkov Telescopes stationed at the South Pole as part of the IceCube Neutrino Observatory. Each telescope features a 61 SiPM pixel based camera with a Fresnel lens imaging on to it, resulting in a field-of-view of 12 degrees. The main goals of IceAct include the calibration of the IceTop surface array and the in-ice detector, as well as improving cosmic-ray composition studies. An agreement and understanding of the measured data and simulation is vital to reconstruct relevant parameters of cosmic-ray-induced extensive air showers for IceAct. Detailed comparisons allow the investigation of possible mismatches, their causes, and impact on reconstruction performance. In this talk we present three years of measured data to validate the IceAct simulation.
