cds-question@unistra.frsurveysradio-sourcesphotometryDeep radio continuum surveys provide fundamental constraints on galaxy evolution, but source confusion limits sensitivity to the faintest sources. We present a complete framework for producing high-fidelity deblended radio catalogues from the confused MIGHTEE maps using the probabilistic deblending framework XID+ and prior positions from deep multi-wavelength data in the COSMOS field. Applied to the ~1.3deg^2^ area of the MIGHTEE-COSMOS field, this procedure yields a deblended catalogue of 89,562 sources. We also define a recommended high-fidelity sample of 20757 sources, based on detection significance, flux density, and goodness-of-fit.2026MNRAS.547ag285Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/547/G285CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/258/11 : The COSMOS2020 catalog (Weaver+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/547/G285https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/547/G285http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/547/G285https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/547/G285https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/547/G285http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/547/G285GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/547/G285/tablee1 (The Radio-Likely deblended catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/547/G285/tablee1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/547/G285/tablee1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/547/G285/tablee1?GETtext/xml+votable180.050000true149.9907170249691.59821310007760.005555555555555556Cone search capability for table J/MNRAS/547/G285/tablee2 (The Comprehensive deblended catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/547/G285/tablee2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/547/G285/tablee2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/547/G285/tablee2?GETtext/xml+votable180.050000true149.98409292376411.59266753869180.0055555555555555565/6814 6/27245 27247 273448.613890125444795e-25 8.613890125444795e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/547/G285?format=asciiRadiodefaultJ/MNRAS/547/G285/tablee1The Radio-Likely deblended cataloguerecnoRecord number assigned by the VizieR team.
