cds-question@unistra.frstar-atlasesspectroscopyAn increasing number of high-resolution stellar spectra is available today thanks to many past and ongoing spectroscopic surveys. Consequently, numerous methods have been developed to perform an automatic spectral analysis on a massive amount of data. When reviewing published results, biases arise and they need to be addressed and minimized. We are providing a homogeneous library with a common set of calibration stars (known as the Gaia FGK benchmark stars) that will allow us to assess stellar analysis methods and calibrate spectroscopic surveys. High-resolution and signal-to-noise spectra were compiled from different instruments. We developed an automatic process to homogenize the observed data and assess the quality of the resulting library.2014A&A...566A..98Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/566/A98CatalogResearchIsServedByTAP VizieR generic servicerelated-toIII/281 : Gaia FGK benchmark stars v2.1 (Jofre+, 2018)J/A+A/564/A133 : Gaia FGK benchmark stars: metallicity (Jofre+, 2014)J/A+A/582/A81 : Gaia FGK benchmark stars: abundances (Jofre+, 2015)J/A+A/592/A70 : Gaia FGK stars: low-metallicities candidates (Hawkins+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/566/A98https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/566/A98http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/566/A98https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/566/A98https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/566/A98http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/566/A98GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapAssociated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/566/A98defaultJ/A+A/566/A98/listList of FITS spectra for 33 stars + the SunrecnoRecord number assigned by the VizieR team.
