On the prospects of cross-calibrating the Cherenkov Telescope Array with an airborne calibration platform

Popis výsledku v původním jazyce

Recent advances in unmanned aerial vehicle (UAV) technology have made UAVs an attractive possibility as an airborne calibration platform for astronomical facilities. This is especially true for arrays of telescopes spread over a large area such as the Cherenkov Telescope Array (CTA). In this paper, the feasibility of using UAVs to calibrate CTA is investigated. Assuming a UAV at 1km altitude above CTA, operating on astronomically clear nights with stratified, low atmospheric dust content, appropriate thermal protection for the calibration light source and an onboard photodiode to monitor its absolute light intensity, inter calibration of CIA's telescopes of the same size class is found to be achievable with a 6 - 8% uncertainty. For cross-calibration of different telescope size classes, a systematic uncertainty of 8 - 10% is found to be achievable.
