cds-question@unistra.frvisible-astronomyspectroscopystellar-agesstellar-masseschemical-abundancesradial-velocitystellar-spectral-typesWe present reprocessed flux-calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025nm, which can be used for stellar population synthesis. The spectra are provided in the two versions having spectral resolving power R=20000 and R=80000. Raw spectra from the ESO data archive were re-reduced using the latest version of the UVES data reduction pipeline with some additional algorithms that we developed. The most significant improvements in comparison with the original UVES-POP release are (i) an updated echelle order merging, which eliminates "ripples" present in the published spectra; (ii) a full telluric correction; (iii) merging of nonoverlapping UVES spectral setups taking into account the global continuum shape; (iv) a spectrophotometric correction and absolute flux calibration; and (v) estimates of the interstellar extinction. For 364 stars from our sample, we computed atmospheric parameters Teff, surface gravity logg, metallicity [Fe/H], and {alpha}-element enhancement [{alpha}/Fe] by using a full-spectrum fitting technique based on a grid of synthetic stellar atmospheres and a novel minimization algorithm. We also provide projected rotational velocity vsini and radial velocity vrad estimates. The overall absolute flux uncertainty in the reprocessed data set is better than 2%, with subpercent accuracy for about half of the stars. A comparison of the recalibrated UVES-POP spectra with other spectral libraries shows a very good agreement in flux; at the same time, Gaia DR3 BP/RP spectra are often discrepant with our data, which we attribute to spectrophotometric calibration issues in Gaia DR3.2023ApJS..266...11Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/266/11CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/pastel : The PASTEL catalogue (Soubiran+, 2016-)B/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)II/84 : 13-color photometry of 1380 bright stars (Johnson+ 1975)I/259 : The Tycho-2 Catalogue (Hog+ 2000)III/218 : ELODIE archive (Prugniel+, 2001)III/232 : STELIB: A library of stellar spectra at R~2000 (Le Borgne+, 2003)I/337 : Gaia DR1 (Gaia Collaboration, 2016)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+AS/146/217 : Library of Spectra (0.5-2.5um) of Cool Stars (Lancon+ 2000)J/A+A/407/1157 : UVES sky atlas (Hanuschik+, 2003)J/A+A/418/551 : Gal. disk stars abundances and velocities (Mishenina+, 2004)J/ApJS/152/251 : Indo-US library of coude feed stellar sp.
