MeerKAT unclassified radio rings: Catalogue of 164 unclassified compact radio rings discovered with MeerKAT

This catalogue provides detailed information for 164 unclassified compact (r<1 arcmin) radio rings discovered using MeerKAT data. The data originates from two key surveys: the SARAO MeerKAT Galactic Plane Survey (SMGPS) and the Galactic Center Mosaic. The catalogue includes coordinates, angular sizes, flux density measurements (with associated uncertainties), and multiwavelength crossmatch information for all 164 rings, as well as tentative classification tags for a subset of the sources. For a comprehensive analysis and further details on the selection and characterization of the rings, please see Bordiu et al. 2025.
