cds-question@unistra.frglobular-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryWe present wide-field, ground-based Johnson-Cousins UBVRI photometry for 48 Galactic globular clusters based on almost 90000 public and proprietary images. The photometry is calibrated with the latest transformations obtained in the framework of our secondary standard project, with typical internal and external uncertainties of order a few millimagnitudes. These data provide a bridge between existing small-area, high-precision HST photometry and all sky-catalogues from large surveys like Gaia, SDSS, or LSST. For many clusters, we present the first publicly available photometry in some of the five bands (typically U and R). We illustrate the scientific potential of the photometry with examples of surface density and brightness profiles and of colour-magnitude diagrams, with the following highlights: (i) we study the morphology of NGC 5904, finding a varying ellipticity and position angle as a function of radial distance; (ii) we show $U$-based colour-magnitude diagrams and demonstrate that no cluster in our sample is free from multiple stellar populations, with the possible exception of a few clusters with high and differential reddening or field contamination, for which more sophisticated investigations are required. This is true even for NGC 5694 and Terzan 8, that were previously considered as (mostly) single-population candidates.2019MNRAS.485.3042Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/485/3042CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/110/533 : BR photometry of Fornax bright stars (Stetson+ 1998)J/PASP/115/413 : BVI photometry in the open cluster NGC 6791 (Stetson+, 2003)J/PASP/117/1325 : BVRI photometry in NGC 4147 (Stetson+, 2005)J/PASP/126/616 : Variable stars in Leo I dSph (Stetson+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/485/3042https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/485/3042http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/485/3042https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/485/3042https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/485/3042http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/485/3042GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/485/3042/table2 (Cluster list and fits image informations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/485/3042/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/485/3042/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/485/3042/table2?GETtext/xml+votable180.050000true6.015125-72.07961110.005555555555555556Cone search capability for table J/MNRAS/485/3042/table4 (Final catalogue -- updated version from the author)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/485/3042/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/485/3042/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/485/3042/table4?GETtext/xml+votable180.050000true138.0609167-64.86497220.0055555555555555565/2584 3101 4772 7854 8560 10252 10781 6/8512-8513 9430 9433 9436-9438 9664 9666 12425 12427-12428 12529 12531-12532 12534 12941 12943 12954 16645 16647 16656 16658 17099 17102 17121 17124 21011 21017 21019-21020 24841-24843 25873 25876 27973 27975 27981 27984 27986 27992 28066-28067 28073 28966-28967 28972-28973 29805 29807 29816 29818 29865 29867-29868 29870 30299 30321 30995 30998 31018-31019 31104-31105 31113-31115 31410-31411 31722-31723 33321 33323 33634-33635 33640-33641 36971 36974 37057 37291 37294 37633 37636 38464-38465 38467-38468 39640 39642 41257 41260 41507 41511 41513 41517 41522 41528 41846 41852 42700-42701 42954-42955 42977 43225 43227-43228 43230 44083-44084 44086-44087 44214-44215 44220-44221 44987 45802 47125 47127 47168 47170 47901-47903 47970-47971 47976-47977 48423 48429 48434 48440 48941 48952 489542.367228618189496e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/485/3042?format=asciiOpticalInfrareddefaultJ/MNRAS/485/3042/table1Observation summaryrecnoRecord number assigned by the VizieR team.
