cds-question@unistra.frglobular-star-clustersphotometryastrometryproper-motionsWe have used HST imaging of the central regions of the globular cluster 47 Tucanae (=NGC 104), taken with the WFPC2 and ACS instruments between 1995 and 2002, to derive proper motions and U- and V-band magnitudes for 14366 stars within 100 (about 5 core radii) of the cluster center. This represents the largest set of member velocities collected for any globular cluster. The stars involved range in brightness from just fainter than the horizontal branch of the cluster to more than 2.5mag below the main-sequence turnoff. In the course of obtaining these kinematic data, we also use a recent set of ACS images to define a list of astrometrically calibrated positions (and F475W magnitudes) for nearly 130000 stars in a larger, 3x3 central area. We describe our data reduction procedures in some detail and provide the full position, photometric, and velocity data.2006ApJS..166..249Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/166/249CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/93/293 : Astrometry of globular clusters (47 Tuc) (Tucholke 1992)J/ApJS/85/293 : HST Observations of core of 47 Tuc (de Marchi+ 1993)J/A+A/391/945 : HST photometry of 74 galactic globular clusters (Piotto+, 2002)J/ApJ/625/796 : X-ray sources in the globular cluster 47 Tuc (Heinke+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/166/249https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/166/249http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/166/249https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/166/249https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/166/249http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/166/249GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/166/249/table3 (Stars used for astrometric calibration, and the resulting cluster center point/star)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/166/249/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/166/249/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/166/249/table3?GETtext/xml+votable180.050000true6.0195417-72.08293890.005555555555555556Cone search capability for table J/ApJS/166/249/table4 (129733 stars in the Master Frame)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/166/249/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/166/249/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/166/249/table4?GETtext/xml+votable180.050000true6.10329-72.1093040.005555555555555556Cone search capability for table J/ApJS/166/249/table5 (Proper motions and displacement data for 14366 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/166/249/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/166/249/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/166/249/table5?GETtext/xml+votable180.050000true6.03120889-72.105878060.0055555555555555566/333213.352923723967259e-19 7.605786964834612e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/166/249?format=asciiOpticaldefaultJ/ApJS/166/249/table3Stars used for astrometric calibration, and the resulting cluster center point/starrecnoRecord number assigned by the VizieR team.
