cds-question@unistra.frstellar-atmospheresstar-atlaseseffective-temperaturemetallicityThe spectral predictions of stellar population models are not as accurate in the ultra-violet (UV) as in the optical wavelength domain. One of the reasons is the lack of high-quality stellar libraries. The New Generation Stellar Library (NGSL), recently released, represents a significant step towards the improvement of this situation. To prepare NGSL for population synthesis, we determined the atmospheric parameters of its stars, we assessed the precision of the wavelength calibration and characterised its intrinsic resolution. We also measured the Galactic extinction for each of the NGSL stars. For our analyses we used ULySS, a full spectrum fitting package, fitting the NGSL spectra against the MILES interpolator. We find that the wavelength calibration is precise up to 0.1pix, after correcting a systematic effect in the optical range. The spectral resolution varies from 3{AA} in the UV to 10{AA} in the near-infrared (NIR), corresponding to a roughly constant reciprocal resolution R~1000 and an instrumental velocity dispersion 130km/s. We derived the atmospheric parameters homogeneously. The precision for the FGK stars is 42K, 0.24 and 0.09dex for Teff, logg and [Fe/H], respectively. The corresponding mean errors are 29K, 0.50 and 0.48dex for the M stars, and for the OBA stars they are 4.5 percent, 0.44 and 0.18dex. The comparison with the literature shows that our results are not biased.2012A&A...538A.143Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/538/A143CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/218 : ELODIE archive (Prugniel+, 2001)http://archive.stsci.edu/prepds/stisngsl : NGSL library home pagehttp://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/A+A/538/A143https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/538/A143http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/538/A143https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/538/A143https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/538/A143http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/538/A143GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/538/A143/param (Physical parameters adopted by this work)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/538/A143/param?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/538/A143/param?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/538/A143/param?GETtext/xml+votable180.050000true213.33226648.61112720.0055555555555555566/49 137 351 373 428 798 811 819 915 987 1293 1408 1556 1603 1642 1696 1749 1873 2460 2499 2664 2678 2737 2746 2970 2973 2997 3026 3199 3266 3395 3430 3494 3639 3678 3712 3718 3777 3865 3970 4091 4095 4191 4206 4286 4298 4322 4373 4419 4512 4698 4820 4846 5195 5420 5490 5531 5534 5622 5624 5805 6036 6058 6082 6153 6160 6183 6472 6601 6728 6776 6792 7064 7117 7177 7186 7240 7334 7413 7683 7710 7746 7798 8009 8068 8296 8332 8476 8510 8671 8803 8926 9048 9054 9520 9680 9717 9753 9792 9831 9836 9847 9996 10055 10375 10504 10595 10696 10783 10811 11197 11250 11441 11473 11599 11636 11722 11806 11885 11929 11959 12056 12082 12179 12396 12477 12544 12621 12793 12934 13025 13028 13114 13132 13148 13238 13301 13332 13829 14151 14209 14298 14373 14419 14522 14630 14679 14690 14734 14743 14767 14875 14931 14968 15021 15097 15364 15530 15628 15658 15850 15901 15937 15980 16069 16115 16213 16629 16834 17028 17266 17395 17576 17955 18028 18035 18204 18425 18821 18887 18978 18990 19099 19113 19179 19192 19206 19347 19448 19676 19924 20322 20532 20661 20804 21099 21233 21269 21389 21438 21515 21723 22106 22184 22205 22211 22518 22558 22773 22868 23190 23230 23323 23421 23567 23592 23637 23893 23922 23974 24151 24179 24565 24793 24839 24866 24924 25051 25278 25444 25569 25601 25607 25789 25875 25919 26110 26289 26304-26305 27033 27088 27143 27322 27498 27512 27641 27694 27857 27871 27903 27991 28006 28137 28208 28252 28336 28491 28915 29138 29490 29593 29596 29703 29769 30064 30078 30167 30175 30179 30188 30221 30257 30304 30307 30315 30330 30374 30404 30411 30434 30450 30456 30467 30659 30709 30878 30893 30939 30958 30970 31011 31101 31284 31448 31488 31683 31686 31751-31752 31756-31757 31760 31767 31769 31794-31795 31805 32019 32140 32181 32441 32580 32621 32731 33018 33027 34171 34181 35813 36035 36221 36526 36651 36664 36697 36745 37664 37843 37932 39413 39709 39745 39853 39888 39893 39907 39916 39923 40336-40337 40580 40716 40750 40795 40882 40944 41247 41659 42081 43127 43693 43720 44208 44281 44499 44669 44771 44816 44860 44883 45837 46776 47337 47930 48281 48299 48525 48731 48767 48856 49142https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/538/A143?format=asciiOpticaldefaultJ/A+A/538/A143/paramPhysical parameters adopted by this workSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
