Distribution of stellar parameters obtained with SPEEM for the gold sample. Left: distribution of stellar parameters Teff and log g. The points are color-coded according to the number of stars, indicating the sample is mostly composed by main sequence stars with spectral types F and G. Right: the distribution of [Fe/H] has two peaks related to the stellar populations of the thick disk at [Fe/H] ~ −0.4 and the halo at [Fe/H] ~ −1.6.
