Cross Calibration of the H.E.S.S. Telescopes — •David Jankowsky and Ira Jung-Richardt — ECAP, Universität Erlangen-Nürnberg

The H.E.S.S. experiment consists of five imaging atmospheric Cherenkov telescopes. Four smaller, identical ones have a mirror area of 108 m² and a larger one that has a mirror area of 614 m². To guarantee high quality data and the best possible physical output it is essential that all data are well understood. This talk presents a possible method to check the responses of such mixed telescope systems: the inter and cross calibration. The main idea behind this calibration is to compare the reconstructed image amplitudes (number of measured photo electrons) or energies of the individual telescopes pairwise and to search for differences in the responses. To illustrate the usability of the methods and their implications on data taking without systematical effects from the telescope array, this talk shows results which were obtained with the help of Monte Carlo simulations.
