cds-question@unistra.frmetallicityatomic-physicsThe homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it because of the diversity of the spectroscopic analysis methods used within a survey, such as spectrum synthesis and the equivalent width method. To solve this problem, constraints to the spectroscopic analysis can be set, such as the use of a common line-list. We present a procedure for selecting the best spectral lines from a given input line-list, which then allows us to derive accurate stellar parameters with the equivalent width method.2014A&A...561A..21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/561/A21CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/458/873 : Metal-rich solar-type stars stellar parameters (Sousa+, 2006)J/A+A/497/563 : Chemical abundances of 451 stars (Neves+, 2009)J/A+A/512/A13 : EW-Teff calibration for solar-type stars (Sousa+, 2010)J/A+A/526/A99 : Metal-poor solar-type stars spectroscopy & massesJ/A+A/544/A106 : p-mode frequencies of the solar twin 18 Sco (Bazot+, 2012)J/A+A/555/A150 : Cool solar-type stars precise parameters (Tsantaki+, 2013)J/ApJ/720/1592 : Abundances of solar analogs with planets (Hernandez+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/561/A21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/561/A21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/561/A21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/561/A21https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/561/A21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/561/A21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/561/A21/table2Atomic parameters of the spectral linesrecnoRecord number assigned by the VizieR team.
