Fundamental parameters and abundances of metal-poor stars: the SDSS standard BD +17 4708
The atmospheric parameters and iron abundance of the Sloan Digital Sky Survey (SDSS) spectrophotometric standard star BD +17 4708 are critically examined using up-to-date Kurucz model atmospheres, LTE line formation calculations, and reliable atomic data. We find Teff=6141 ± 50 K, log g=3.87 ± 0.08, and [Fe/H]=-1.74 ± 0.09. The line-of-sight
