Toward a Public MAGIC Gamma-Ray Telescope Legacy Data Portal

TL;DR

This paper discusses the development of a public data portal for MAGIC gamma-ray telescope data, aiming to enhance accessibility, usability, and legacy preservation of observational data for the scientific community.

Contribution

It introduces plans to expand MAGIC data formats, include multi-wavelength datasets, and provide raw and processed data for broader scientific analysis.

Findings

Published data from over 60 sources including spectral energy distributions and light curves.

Plans to include full multi-wavelength datasets and raw event lists.

Development of a comprehensive legacy data portal for MAGIC observations.

Abstract

The MAGIC telescopes are one of the three major IACTs (Imaging Atmospheric Cherenkov Telescopes) for observation of gamma rays in the TeV regime currently operative. MAGIC functions since 2003, and has published data from more than 60 sources, mostly blazars. MAGIC already provides astronomical \texttt{.fits} files with basic final scientific products such as spectral energy distributions, light curves and skymaps from published results. In future, the format of the files can be complemented with further relevant information to the community: a) by including the full multi-wavelength dataset enclosed in a publication, b) providing data in alternative easy-to-use formats such as ASCII or ECSV, which are accessible with other commonly used packages such as \texttt{astropy} or \texttt{gammapy}. Finally, besides high level products, activities have started to provide photon event lists and instrument response functions in a format such that scientists within and outside the community are allowed to perform higher level analysis. A second aim is to provide a full legacy of MAGIC data. This contribution will illustrate the achievements and plans of this activity.
