cds-question@unistra.frmagellanic-cloudsinfrared-photometryvisible-astronomyWide-band photometryccd-photometryWe present photometry and a preliminary interpretation of a UBVR survey of the Large and Small Magellanic Clouds, which covers 14.5 deg^2^ and 7.2deg^2^, respectively. This study is aimed at obtaining well-calibrated data on the brighter, massive stars, complementing recent, deeper CCD surveys. Our catalog contains 179,655 LMC and 84,995 SMC stars brighter than V~18.0, and is photometrically complete to U~B~V~15.7 and R~15.2, although stars in crowded regions are selectively missed. We compare our photometry to that of others, and describe the need for gravity-dependent corrections to our CCD U-band photometry. We provide a preliminary cross-reference between our catalog stars and the stars with existing spectroscopy.2002ApJS..141...81Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/II/236CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/221 : The Magellanic Catalogue of Stars - MACS (Tucholke+ 1996)II/65 : VBUWL photometry of blue stars in and between the MC (Wamsteker 1981)II/228 : DENIS Catalogue toward Magellanic Clouds (Cioni+ 2000)II/232 : UBV photometry of selected regions in the MCs (Braun 2001)III/113 : LMC members deep objective-prism survey (Sanduleak, 1989)J/AJ/116/180 : Magellanic clouds ultraviolet observations (Parker+ 1998)J/AJ/120/1808 : Stroemgren photometry in LMC disk (Cole+, 2000)J/AJ/123/855 : Magellanic Clouds Photometric Survey.
