cds-question@unistra.frglobular-star-clustersvisible-astronomybroad-band-photometryCCD photometry in B and V, taken with the RCA camera at the CTIO 4-meter telescope, is reported for 8800 stars in the field of 47 Tuc (= NGC 104 = C0021-723). Our data, reduced through the DAOPHOT code, comprise results from two long-exposure frame pairs in which the photometry extends from the cluster turnoff down to V~24, and two other short-exposure fields nearer to the cluster center which precisely define the giant and horizontal branches. Color-magnitude diagrams are presented, statistically corrected for background contamination from the Small Magellanic Cloud halo, and a composite CMD and luminosity function are constructed for the entire cluster, covering an 11-magnitude range in luminosity.1987PASP...99..739Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/99/739CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+AS/93/293 : Astrometry of globular clusters (47 Tuc) (Tucholke 1992)J/A+AS/106/161 : (V,I) photometry in NGC 6356 and 47 Tuc (Bica+ 1994)J/A+AS/128/19 : Variable stars in 47 Tuc fields 104A-E (Kaluzny+ 1998)J/AJ/110/1699 : F-P observations of globular clusters (Gebhardt+ 1995)J/ApJS/85/293 : HST Observations of core of 47 Tuc (de Marchi+ 1993)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/99/739https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/99/739http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/99/739https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/99/739https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/99/739http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/99/739GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/PASP/99/739/tablesPhotometry for stars in the F1 to F4 fieldsrecnoRecord number assigned by the VizieR team.
