cds-question@unistra.frpopulation-ii-starsmetallicityspectroscopyWe present the stellar parameters, abundances, associated errors and the linelist of a set of 23 metal-poor and very metal-poor halo stars. Stellar parameters and chemical abundances were derived in a line-by-line differential analysis from equivalent widths of UVES/VLT spectra. The differential analysis provided us unprecedented small data scatter and errors. Our sample, along with data from different authors in different metallicity ranges, allowed us to do an extensive comparison of the chemical abundances with the predictions of a Galaxy chemical evolution model.2017A&A...608A..46Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/608/A46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/608/A46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/608/A46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/608/A46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/608/A46https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/608/A46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/608/A46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/608/A46/tablea (Stellar parameters and abundances (tables A1-A6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/608/A46/tablea?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/608/A46/tablea?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/608/A46/tablea?GETtext/xml+votable180.050000true268.680127520.27123390.0055555555555555566/4376 6159 8999 12621 12645 13020 14385 18887 20680 25385 25554 25948 26289 31748 32343 39446 39692 39911 40567 41259 43445 43575 47389https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/608/A46?format=asciiOpticaldefaultJ/A+A/608/A46/linelistLinelistrecnoRecord number assigned by the VizieR team.
