LSST Cross-matches for EMUCAT
Add Rubin optical counterparts and value-added measurements to the EMUCAT radio catalogue.
This project develops Rubin LSST cross-matches for EMUCAT, the EMU radio-source catalogue. Matching methods account for differences in angular resolution and source structure, with tests of direct radio–optical matching and WISE as an intermediate catalogue using LSDB and HATS data.
