In this paper, we update the previous point source UV catalogue of M33, created using the Ultraviolet Imaging Telescope (UIT), using data from the Galaxy Evolution Explorer (GALEX). We utilize point spread function photometry to optimally photometer sources in the crowded regions of the galaxy, and benefit from GALEX's increased sensitivity compared to UIT. We match our detections with data from the Local Group Galaxies Survey to create a catalogue with photometry spanning from the far-UV through the optical for a final list of 24738 sources. All of these sources have far-UV (FUV; 1516{AA}), near-UV (NUV; 2267{AA}) and V data, and a significant fraction also have U, B, R and I data as well. We also present an additional 3000 sources that have no matching optical counterpart. We compare all of our sources to a catalogue of known WR stars in M33 and find that we recover 114 of 206 stars with spatially-coincident UV point sources. Additionally, we highlight and investigate those sources with unique colours as well as a selection of other well-studied sources in M33.2015MNRAS.450.3811Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/450/3811CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/131/2478 : M31 and M33 UBVRI photometry, LGGS (Massey+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/450/3811https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/450/3811http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/450/3811https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/450/3811https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/450/3811http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/450/3811GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/450/3811/table1 (UIT sources that were recovered using GALEX data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/450/3811/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/450/3811/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/450/3811/table1?GETtext/xml+votable180.050000true23.13330.582750.005555555555555556Cone search capability for table J/MNRAS/450/3811/table2 (Our UV sources that had optical counterparts from the LGGS (Massey et al, 2006, J/AJ/131/2478))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/450/3811/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/450/3811/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/450/3811/table2?GETtext/xml+votable180.050000true23.7524430.710680.005555555555555556Cone search capability for table J/MNRAS/450/3811/table3 (Those UV sources that did not have an optical counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/450/3811/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/450/3811/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/450/3811/table3?GETtext/xml+votable180.050000true23.6249730.107370.0055555555555555566/2153-2155 2240-22412.367228618189496e-19 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/450/3811?format=asciiUVOpticalInfrareddefaultJ/MNRAS/450/3811/table1UIT sources that were recovered using GALEX datarecnoRecord number assigned by the VizieR team.
