Automatized Pulsar Analysis for the MAGIC Telescopes — •Jan Lukas Schubert and Stefan Fröse for the MAGIC collaboration — TU Dortmund University, Dortmund, Germany

The MAGIC telescopes are Imaging Air Cherenkov Telescopes which are used for gamma-ray detection in the GeV to TeV range. Thanks to an analog trigger system, dubbed Sum-Trigger-II, low-energy observations with a threshold as low as ~15 GeV can be made, enabling the MAGIC telescopes to perform comparably low energetic analyses such as pulsar analyses. These data requires a dedicated treatment adapted to the low energies. The automatization of the analysis of Sum-Trigger-II data was implemented in the autoMAGIC project, which aims to automatize the entire MAGIC analysis chain. It produces DL3 data, which represent a standard data format for gamma-ray astronomy.

A workflow for the pulsar timing and the pulsar analysis based on DL3 files produced with autoMAGIC was implemented and delivers results comparable to the currently used pulsar analysis tools in MAGIC. In the future, the automatization of the analysis of Sum-Trigger-II data could be used for further optimizations of the low-energy analysis as well as for comparisons of low-energy data from MAGIC and the LST. Combined with the automatic pulsar analysis, this will enable the possibility of performing long-term pulsar analyses with comparably little effort.
