MASER: an Astronomy Open Science Pilot within the OSTrails project

The MASER (Measuring Analyzing and Simulating Emissions in Radio frequencies, https://maser.lesia.obspm.fr/) service proposes a set of tools for low frequency radio astronomy, allowing the research teams to access, dispaly, analyse, model and publish radio astronomy data products. Thanks to the EU-funded OSTrails project (https://ostrails.eu/), the MASER team is developing an open science pilot implementing and testing the three pillars of OSTrails:- Plan: adopting and implementing a Data Management Plan tool, to streamline the data life cycle management and prepare the publication of the MASER datasets.- Track: linking datasets, services, instruments, researchers and institutions in a knowledge graph, to enhance data discoverability as well as better measuring the impact of the MASER service- Assess: design adapted FAIR evalution metrics and tests for astronomy, to assess the FAIRness of the research products published in MASER.We present the first results of the OSTrails developments and how this applies to MASER and the astronomy community.This project has received funding from the European Union's Horizon Europe framework programme under grant agreement No. 101130187.
