“…They are used in stereoscopy (section 1), where the core distance is obtained as an intersection of axes of multiple images. In a previous analysis of TAIGA simulation we also followed this approach ("hybrid scaled width" [9]), however, in the present work the scaling procedure is applied to the selection cuts. An additional difference of the present approach is scaling the cuts depending on both the core distance and primary energy from the timing array of TAIGA.…”

Our previous steps [9] followed standard IACT "scaled cuts" analysis using total number of photoelectrons in an image ("image size") instead of the energy. Fig.…”

Abstract. This work is a methodical study on hybrid reconstruction techniques for hybrid imaging/timing Cherenkov observations. This type of hybrid array is to be realized at the gamma-observatory TAIGA intended for very high energy gamma-ray astronomy (> 30 TeV). It aims at combining the cost-effective timing-array technique with imaging telescopes. Hybrid operation of both of these techniques can lead to a relatively cheap way of development of a large area array. The joint approach of gamma event selection was investigated on both types of simulated data: the image parameters from the telescopes, and the shower parameters reconstructed from the timing array. The optimal set of imaging parameters and shower parameters to be combined is revealed. The cosmic ray background suppression factor depending on distance and energy is calculated. The optimal selection technique leads to cosmic ray background suppression of about 2 orders of magnitude on distances up to 450 m for energies greater than 50 TeV.
