cds-question@unistra.frspectroscopystellar-massesstellar-ageseffective-temperaturemetallicityTemperature, surface gravity, and metallicity are basic stellar atmospheric parameters necessary to characterize a star. There are several methods to derive these parameters and a comparison of their results often shows considerable discrepancies, even in the restricted group of solar-type FGK dwarfs. We want to check the differences in temperature between the standard spectroscopic technique based on iron lines and the infrared flux method (IRFM). We aim to improve the description of the spectroscopic temperatures especially for the cooler stars where the differences between the two methods are higher, as presented in a previous work. Our spectroscopic analysis was based on the iron excitation and ionization balance, assuming Kurucz model atmospheres in LTE. The abundance analysis was determined using the code MOOG. We optimized the line list using a cool star (HD 21749) with high resolution and high signal-to-noise spectrum, as a reference in order to check for weak, isolated lines. We test the quality of the new line list by re-deriving stellar parameters for 451 stars with high resolution and signal-to-noise HARPS spectra, that were analyzed in a previous work with a larger line list. The comparison in temperatures between this work and the latest IRFM for the stars in common shows that the differences for the cooler stars are significantly smaller and more homogeneously distributed than in previous studies for stars with temperatures below 5000K.2013A&A...555A.150Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/555/A150CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/Nat/486.375 : Stellar parameters of KOI stars (Buchhave+, 2012)J/A+A/545/A32 : Chemical abundances of 1111 stars (Adibekyan+, 2012)J/A+A/533/A141 : Stellar parameters for 582 HARPS FGK stars (Sousa+, 2011)J/A+A/526/A99 : Metal-poor solar-type stars spectro. & masses (Sousa+, 2011)J/A+A/530/A138 : Geneva-Copenhagen survey re-analysis (Casagrande+, 2011)J/A+A/512/A13 : EW-Teff calibration for solar-type stars (Sousa+, 2010)J/A+A/512/A54 : Teff and Fbol from Infrared Flux Method (Casagrande+, 2010)J/A+A/497/563 : Chemical abundances of 451 stars (Neves+, 2009)J/A+A/487/373 : Spectroscopic parameters of 451 HARPS-GTO stars (Sousa+, 2008)J/ApJ/687/1264 : Age estimation for solar-type dwarfs (Mamajek+, 2008)J/A+A/469/783 : Code for automatic determination of EW (ARES) (Sousa+, 2007)J/MNRAS/371/879 : Effective temperatures of 215 FGK giants (Kovtyukh+, 2006)J/MNRAS/373/13 : Lower MS stars fundamental param.
