Open Science in Radio Astronomy

The Open Science paradigm and the FAIR principles (Findable, Accessible, Interoperable, Reusable) is aiming to foster scientific return, and reinforce the trust in science production. We present how the Service National d’Observation MASER implements Open Science through a series of existing solutions that have been put together, only adding new pieces where needed.

The MASER service is a “science ready” and “open science” toolbox dedicated to time-domain low frequency radioastronomy. The principal data product in this domain is a “dynamic spectrum”, i.e., a series of consecutive spectra with the same observing configuration. The observed physical phenomena are related to plasma instabilities and energetic particles in magnetized plasma. Hence low frequency radio astronomy is a remote sensing tool for plasma diagnostics.

MASER covers four community needs: 1. Discovering data products, 2. Exploring data collections before downloading TB’s of files, 3. Annotating and then storing and sharing annotations on radio dynamic spectra, 4. Accessing data in Python.

MASER solutions are based on IVOA protocols for data discovery, on IHDEA tools for data explo- ration, and on a dedicated format developed by MASER for the annotations. The service also proposes a data repository for sharing data collections, catalogues and associated documentation, as well as sup- plementary materials associated to papers. Each product of the repository if citable with a DOI, and the landing page contains web semantics annotations (using
