cds-question@unistra.frgalaxiesradial-velocityphotometryWe explore the spatial distribution of stars in the Sculptor dwarf spheroidal (dSph) galaxy over an area of 7.82deg^2^, including coverage of the central region but extending mostly south and east of the dSph core. Two methods are used to identify stars that are most likely associated with the dSph, and these filtered samples of stars are used to map its spatial structure. First, following the method of previous contributions in this series, we utilize Washington M, T_2_+DDO51 photometry to identify red giant branch (RGB) star candidates with approximately the same distance and metallicity as the Sculptor dSph. Second, a prominent blue horizontal branch (BHB) population provides a fairly populous and pure sample of Sculptor stars having broadband colors unlike the bulk of the Galactic field star population. A spectroscopically observed subset of Sculptor candidate stars (147 total stars: ~5% of all Sculptor candidates and ~10% of Sculptor giant candidates) yields a systemic heliocentric velocity for the system of v_hel_=110.43+/-0.79km/s, in good agreement with previous studies.2006AJ....131..375Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/131/375CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/705/328 : Abundance measurements in Sculptor dSph (Kirby+, 2009)J/AJ/130/1065 : Members of the Sculptor dSph galaxy (Coleman+, 2005)J/MNRAS/363/734 : Sculptor dSph variables metal abundances (Clementini+, 2005)J/AJ/128/245 : M giant stars in the Sagittarius dwarf galaxy (Majewski+,J/AJ/110/2747 : Stars in Sculptor dwarf spheroidal galaxy (Schweitzer+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/131/375https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/131/375http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/131/375https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/131/375https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/131/375http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/131/375GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/131/375/table4 (Heliocentric radial velocities of selected stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/131/375/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/131/375/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/131/375/table4?GETtext/xml+votable180.050000true14.7891667-33.84847220.0055555555555555566/35543 35549 35551 35712 35714 35720 357213.5822022962738423e-19 4.272473093760679e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/131/375?format=asciiOpticaldefaultJ/AJ/131/375/table4Heliocentric radial velocities of selected starsrecnoRecord number assigned by the VizieR team.
