cds-question@unistra.frgalaxiesgiant-starsphotometrymetallicityWe present the results of the DART imaging and CaII triplet (CaT) survey of the Fornax dwarf spheroidal galaxy (dSph) at ESO. We collected hundreds of low resolution spectra of Red Giant Branch (RGB) stars in the CaT region, using VLT/FLAMES in Medusa mode, with the GIRAFFE spectrograph (grating LR8, resolving power R~6500). We list the results for the targets with a S/N per Angstrom >10 and an error in velocity <5km/s, because we found this to be the minimum for an accurate determination of velocity and equivalent width. We checked the sample to weed out any spurious object (e.g., broken fibres, background galaxies, foreground stars, spectra not consistent with RGBs). We use a 2.5sigma cut from the system velocity to derive which stars are probable velocity members of the Fornax dSph. We transform the equivalent width of the CaT lines of probable velocity members into metallicity ([Fe/H]) using the relation derived by Rutledge et al. (1997PASP..109..907R) and combining the CaT lines as in Tolstoy et al. (2001MNRAS.327..918T). The errors in [Fe/H] are based on S/N computations and adjusted to agree with repeated measurements.2006A&A...459..423Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/459/423CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/185 : The giant branch of the Fornax dwarf spheroidal galaxy (Sagar+, 1990)J/AJ/127/840 : VRI photometry of Fornax red giants (Pont+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/459/423https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/459/423http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/459/423https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/459/423https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/459/423http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/459/423GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/459/423/table4 (Properties of VLT/FLAMES targets in Fornax dSph)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/459/423/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/459/423/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/459/423/table4?GETtext/xml+votable180.050000true40.4340417-33.76791670.0055555555555555565/8992 6/35882-35883 35972https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/459/423?format=asciiOpticaldefaultJ/A+A/459/423/table4Properties of VLT/FLAMES targets in Fornax dSphrecnoRecord number assigned by the VizieR team.
