The original G4Jy catalogue plus its updated 'multiwavelength' version

The original G4Jy catalogue -- G4Jy_catalogue_18012020.fits (White et al., 2020a, 2020b) -- contains comprehensive radio data (via the GLEAM Extragalatic Catalogue), as well as host-galaxy identifications (in AllWISE) for 86% of the G4Jy Sample. We provide an updated version of the catalogue -- G4Jy_catalogue_28072025.fits (White et al., 2025c, 2025d) -- that includes: 93% identification-completeness, 64% redshift-completeness, optical photometry (via DESI Legacy Surveys DR10), and near-infrared photometry (via 2MASS). The easiest way to combine information from both catalogues is to crossmatch on the radio-centroid positions (centroid_RAJ2000, centroid_DEJ2000).
