cds-question@unistra.frglobular-star-clustersvariable-starseclipsing-binary-starsphotometryDifferential time series photometry has been derived for 46,422 main-sequence stars in the core of 47 Tucanae. The observations consisted of near-continuous 160 s exposures alternating between the F555W and F814W filters for 8.3 days in 1999 July with the Wide Field Planetary Camera 2 on the Hubble Space Telescope. Using Fourier and other search methods, 11 detached eclipsing binaries and 15 W Ursa Majoris stars have been discovered plus an additional 10 contact or near-contact noneclipsing systems. After correction for nonuniform area coverage of the survey, the observed frequencies of detached eclipsing binaries and W UMa stars within 90" of the cluster center are 0.022% and 0.031%, respectively. The data were taken over an 8.3 day period, 1999 July 3-11, during which HST was pointed continuously at 47 Tuc.2001ApJ...559.1060Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/559/1060CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/Sci/292.2290 : Chandra compact binaries in 47 Tuc (Grindlay+, 2001)J/ApJS/85/293 : HST Observations of core of 47 Tuc (de Marchi+ 1993)J/A+A/315/40 : Photometry of the Tuc dwarf galaxy (Saviane, 1996)J/A+AS/128/19 : Variable stars in 47 Tuc fields 104A-E (Kaluzny+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/559/1060https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/559/1060http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/559/1060https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/559/1060https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/559/1060http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/559/1060GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/559/1060/tables (HST photometry of 47 Tuc variables (tables 1-8 of the publication))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/559/1060/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/559/1060/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/559/1060/tables?GETtext/xml+votable180.050000true6.038531389-72.0845961110.0055555555555555566/333213.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/559/1060?format=asciiOpticaldefaultJ/ApJ/559/1060/tablesHST photometry of 47 Tuc variables (tables 1-8 of the publication)SimbadNameSimbad column added by the CDSmeta.idcharVNameStar variable name (2)meta.id;meta.maincharl_PerLimit flag on Permeta.code.errorcharPer?
