cds-question@unistra.frgalaxiesccd-photometryinfrared-photometryvisible-astronomybroad-band-photometryWe present UBVRI photometry obtained from Mosaic images of M31 and M33 using the Kitt Peak National Observatory 4m telescope. We describe our data reduction and automated photometry techniques in some detail, as we will shortly perform a similar analysis of other Local Group galaxies. The present study covered 2.2deg^2^ along the major axis of M31 and 0.8deg^2^ on M33, chosen so as to include all of the regions currently active in forming massive stars. We calibrated our data using photometry from the Lowell 1.1m telescope, and this external method resulted in millimagnitude differences in the photometry of overlapping fields, providing some assurance that our photometry is reliable. The final catalog contains 371781 and 146622 stars in M31 and M33, respectively, where every star has a counterpart in (at least) the B, V, and R passbands. Our survey goes deep enough to achieve 1%-2% photometry at 21mag (corresponding to stars more massive than 20M_{sun}_) and achieves <10% errors at ~U ~B ~V ~R ~I 23mag.2006AJ....131.2478Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/2478CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/115/1894 : M31A eclipsing binaries and Cepheids (Stanek+ 1998)J/AJ/115/1016 : M31B eclipsing binaries and Cepheids (Kaluzny+ 1998)J/AJ/117/2810 : M31C eclipsing binaries and Cepheids (Stanek+, 1999)J/AJ/118/346 : M31D eclipsing binaries and Cepheids (Kaluzny+ 1999)J/AJ/118/2211 : M31F eclipsing binaries and Cepheids (Mochejska+ 1999)J/AJ/122/1383 : DIRECT BVI photometry in M31 (Mochejska+, 2001)J/AJ/121/861 : BVI photometry of central part of M33 (Macri+, 2001)J/AJ/121/870 : BVI photometry of Variables in M33 (Macri+, 2001)J/AJ/121/2032 : DIRECT variables in M33A field (Mochejska+, 2001)J/AJ/122/2477 : DIRECT variables in M33B field (Mochejska+, 2001)J/AJ/126/175 : M31Y eclipsing binaries and Cepheids (Bonanos+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/2478https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/2478http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/2478https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/2478https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/2478http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/2478GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/2478/table4 (M31 Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2478/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2478/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2478/table4?GETtext/xml+votable180.050000true9.25840.20922220.005555555555555556Cone search capability for table J/AJ/131/2478/table5 (M33 Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2478/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2478/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2478/table5?GETtext/xml+votable180.050000true22.942333330.31544440.005555555555555556Cone search capability for table J/AJ/131/2478/table8 (M31 members confirmed by spectroscopy)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2478/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2478/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2478/table8?GETtext/xml+votable180.050000true9.370791740.33550.005555555555555556Cone search capability for table J/AJ/131/2478/table9 (M33 members confirmed by spectroscopy)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/2478/table9?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/2478/table9?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/2478/table9?GETtext/xml+votable180.050000true23.141041730.45802780.0055555555555555566/2154 2155 2240 2241 2619 2622 2623 2666 2667 2705 2708 2709 27523.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/2478?format=asciiOpticalInfrareddefaultJ/AJ/131/2478/table4M31 CatalogrecnoRecord number assigned by the VizieR team.
