The GRBSN webtool: An open-source repository for gamma-ray burst-supernova associations

This paper presents the GRBSN webtool, an open-source data repository coupled to a web interface that hosts the most complete dataset of GRB-SN associations to date. In contrast to repositories of supernova (SN) or gamma-ray burst (GRB) data, this tool provides a multi-wavelength view of each GRB-SN association. GRBSN allows users to view and interact with plots of the data; search and filter the whole database; and download radio, X-ray, optical/NIR photometric and spectroscopic data related to a GRB-SN association. The web interface code and GRB-SN data are hosted on a public GitHub repository, allowing users to upload their own data, flag missing data and suggest improvements. The GRBSN webtool will be maintained by the Space Science group at University College Dublin, Ireland. As the number of confirmed GRB-SN associations increases in the coming years, the GRBSN webtool will provide a robust framework in which to catalogue these associations and their associated data.
