cds-question@unistra.frstellar-atmospheresstar-atlaseseffective-temperaturemetallicityA number of spectroscopic surveys have been carried out or are planned to study the origin of the Milky Way. Their exploitation requires reliable automated methods and softwares to measure the fundamental parameters of the stars. Adopting the ULySS package, we have tested the effect of different resolutions and signal-to-noise ratios (SNR) on the measurement of the stellar atmospheric parameters (effective temperature Teff, surface gravity logg, and metallicity [Fe/H]). We show that ULySS is reliable to determine these parameters with medium-resolution spectra (R~2000). Then, we applied the method to measure the parameters of 771 stars selected in the commissioning database of the Guoshoujing Telescope (GSJT). The results were compared with the SDSS/SEGUE Stellar Parameter Pipeline (SSPP), and we derived precisions of 167K, 0.34dex, and 0.16dex for Teff, logg and [Fe/H] respectively. Furthermore, 120 of these stars are selected to construct the primary stellar spectra template library (Version 1.0) of GSJT, and will be deployed as basic ingredients for the GSJT automated parametrization pipeline.2011RAA....11..924Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/11.924CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/251 : ELODIE library V3.1 (Prugniel+ 2007)J/A+A/525/A71 : Atmospheric parameters for 1273 stars (Wu+, 2011)J/ApJS/152/251 : Indo-US Library of Coude Feed Stellar Spectra (Valdes+, 2004)http://www.noao.edu/cflib : Indo-US library of coude feed stellar spectrahttp://ulyss.univ-lyon1.fr/ : ULySS software package home pagehttp://www.obs.u-bordeaux1.fr/m2a/soubiran/elodie_library.html :https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/11.924https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/11.924http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/11.924https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/11.924https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/11.924http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/11.924GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/11.924/table (Physical parameters adopted by this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/11.924/table?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/11.924/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/11.924/table?GETtext/xml+votable180.050000true132.866806119.464151390.0055555555555555565/1061 1063 1072 1074-1075 6/4249 4276-4278 4320-4321 4323-4326https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/11.924?format=asciiOpticaldefaultJ/other/RAA/11.924/tablePhysical parameters adopted by this workFibFiber ID numbermeta.idintrecnoRecord number assigned by the VizieR team.
