Toward a Public MAGIC Gamma-Ray Telescope Legacy Data Portal

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 .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 XML, which are accessible with other commonly used packages such as 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.

Summary of the 36th ICRC Gamma-ray Indirect sessions

“…Collaboration has released a data set of about 2500 hr of the Galactic plane survey, and another release of a similar amount of extragalactic data is planned [1]. The MAGIC Collaboration at the moment is providing mostly only the machine readable high-level products of the analysis, however in some cases event lists were provided and there is work ongoing on providing a legacy dataset in CTA-like DL3 format [107].…”
