Information on Service 'GLEAM 4-Jy Sample Server'

The GLEAM 4-Jy (G4Jy) Sample Server provides overlays and images to the astronomical community, with the G4Jy Sample defined in White et al. (2020a) and details of cross-identification in White et al. (2020b). As these two bodies of work were completed in conjunction with one another, please cite both when using the products that we make available here.
