cds-question@unistra.frchemical-abundancesgiant-starsgalaxiesspectroscopyglobular-star-clustersinfrared-photometryvisible-astronomybroad-band-photometryWe present measurements of the abundances of chromium, cobalt, and nickel in 4113 red giants, including 2277 stars in globular clusters (GCs), 1820 stars in the Milky Way's dwarf satellite galaxies, and 16 field stars. We measured the abundances from mostly archival Keck/DEIMOS medium-resolution spectroscopy with a resolving power of R~6500 and a wavelength range of approximately 6500-9000{AA}. The abundances were determined by fitting spectral regions that contain absorption lines of the elements under consideration. We used estimates of temperature, surface gravity, and metallicity that we previously determined from the same spectra. We estimated systematic error by examining the dispersion of abundances within mono- metallic GCs. The median uncertainties for [Cr/Fe], [Co/Fe], and [Ni/Fe] are 0.20, 0.20, and 0.13, respectively. Finally, we validated our estimations of uncertainty through duplicate measurements, and we evaluated the accuracy and precision of our measurements through comparison to high-resolution spectroscopic measurements of the same stars.2018ApJS..237...18Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/237/18CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7 (Adelman-McCarthy+, 2009)J/AJ/108/555 : BVI photometry in globular cluster M68 (Walker, 1994)J/AJ/120/1841 : Abundances & Kinematics of Halo & Disk Stars (Fulbright 2000)J/AJ/121/916 : HST obs. of NGC 2298, 5897, 6535, and 6626 (Testa+, 2001)J/ApJ/612/447 : Draco 119 and HD 88609 equivalent widths (Fulbright+, 2004)J/AJ/129/303 : Abundances of stars in M3 and M13 (Cohen+, 2005)J/AJ/129/1607 : Equivalent widths of 4 RGB in NGC 7492 (Cohen+, 2005)J/PASP/117/37 : BVRI photometry in NGC 2419, Pal 4, and Pal 14 (Saha+, 2005)J/ApJ/682/1217 : Abundances in red giants in 7 GCs (Kirby+, 2008)J/ApJ/701/1053 : Abundances of 8 stars in the Draco dSph (Cohen+, 2009)J/ApJ/705/328 : Abundance measurements in Sculptor dSph (Kirby+, 2009)J/ApJ/719/931 : Chemical evolution of the UMi dSph (Cohen+, 2010)J/ApJ/708/560 : Spectroscopy of UMa II and Coma Ber (Frebel+, 2010)J/ApJS/191/352 : Abundances in stars of MW dwarf satellites (Kirby+, 2010)J/A+A/523/A17 : Individual stars in Fornax dSph center (Letarte+, 2010)J/A+A/530/A31 : Stellar param. in 10 globular cluster fields (Lane+, 2011)J/AJ/141/175 : Abundances in M15 RGB/RHB stars (Sobeck+, 2011)J/ApJ/779/102 : Metallicities of RGB stars in dwarf galaxies (Kirby+, 2013)J/MNRAS/429/126 : Atmospheric parameters from Fe lines (Ruchti+, 2013)J/ApJ/819/135 : Lithium-rich giants in globular clusters (Kirby+, 2016)J/A+A/603/A37 : 4 globular clusters RGB and AGB stars (Gruyters+, 2017)J/A+A/616/A12 : Gaia DR2 sources in GC and dSph (Gaia Collaboration+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/237/18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/237/18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/237/18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/237/18https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/237/18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/237/18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/237/18/table3 (*Catalog of abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/237/18/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/237/18/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/237/18/table3?GETtext/xml+votable180.050000true13.064625-26.68463890.005555555555555556Cone search capability for table J/ApJS/237/18/table5 (Comparison to high-resolution spectroscopic abundances)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/237/18/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/237/18/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/237/18/table5?GETtext/xml+votable180.050000true81.0769583-24.52869440.005555555555555556Cone search capability for table J/ApJS/237/18/syst (Spectroscopic targets (table 2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/237/18/syst?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/237/18/syst?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/237/18/syst?GETtext/xml+votable180.050000true15.0391667-33.70888890.0055555555555555566/1133 4410 6021 6023 6032 6051 6389 7416 7417 9436 9664 9666 10008 10183 10336 10337 10444 10769 11691 11694 12405 12531 12943 14489 16647 17121 19091 19094 19097 19456 20001 21017 24843 25873 26457 26980 27207 27213 27226 27574 27580 27975 27981 27984 27986 28136 28361 28966 28967 28972 28973 31416 31417 31451 31592 31692 31723 31757 32468 35549 35720 35969 44427 48434 48440 48698 48764 48798 48824https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/237/18?format=asciiInfraredOpticaldefaultJ/ApJS/237/18/table3*Catalog of abundancesrecnoRecord number assigned by the VizieR team.
