Analysis of the of the 2016 Flaring Period of 1ES1959+650 with the MAGIC Telescopes using the Database Driven Software autoMAGIC — •Justus Koczwara and Felix Wersig — TU Dortmund University, Dortmund, Germany

When entering the atmosphere, the high-energy gamma-rays interact with atoms and produce showers of high-energy charged particles that move faster than the speed of light in the air, emitting Cherenkov radiation. This effect enables us to observe the remnants of these interactions and reconstruct the energy and origin of a gamma ray from the optical image taken by a ground-based telescope. The MAGIC telescopes are a system of so-called Imaging Air Cherenkov Telescopes that have used this detection method since 2003, accumulating a large dataset over the years. As the standard way of analysing MAGIC telescope data includes various manual interventions, increasing the rate of potential error sources, and is very time-consuming, the database-driven software tool autoMAGIC was developed to automate the low-level analysis up to the community-standard data level 3. In the scope of this work, the strong flaring periods of the BL Lac blazar 1ES 1959+650 in 2016 were re-analyzed as a cross-check for a manual low-level analysis, performing the low-level analysis with autoMAGIC and a high-level analysis with Gammapy. The results from this analysis are then compared with the results of the manual analysis published in a paper by the MAGIC Collaboration to understand whether flare characteristics found in the manual analysis can be reproduced in the autoMAGIC analysis.
