Abstract
The ASTRI Mini-Array is an international project to build and operate a facility to study astronomical sources emitting very high-energy 𝛾-rays in the 1–200 TeV energy band. It will be an array of nine small-sized (4-m diameter) and large field of view (∼10 deg) imaging atmospheric Cherenkov telescopes (IACTs) currently under deployment at the Observatorio del Teide (Tenerife, Spain).
Thanks to its expected performance, the ASTRI Mini-Array will be important to perform deep Galactic and extra-galactic 𝛾-ray observations. In order to achieve the final science products, the high-level scientific analysis needs the Instrument Response Functions (IRFs) and event-lists of data level 3 (DL3) as primary inputs. IRFs are derived from the reduction of suitable Monte Carlo simulations, while the event-lists are achieved from the proper reconstruction and selection of the raw data collected during observations. The IRFs include all needed quantities to properly assess the true spectral and spatial properties of the 𝛾-ray emitters. The IRFs generation mainly depends on hardware settings or configurations, telescope pointing direction, data-taking conditions (e.g.
level of the Night Sky Background, atmospheric transparency, etc.) and analysis methods (e.g. reconstruction methods, cut optimisation criteria, etc.). In this contribution, we describe the tools and methods that are currently implemented in the data-reduction software package of the ASTRI
Project to generate DL3 IRFs and event-lists.
