Normalized probability density metallicity [Fe/H] with uncertainty bands for kinematic groups listed in the legend. The chemically defined halo stars were excluded from the Splash and chemicall -defined disk stars were excluded from the rest of the groups. The plot is generated using a kernel density estimation (KDE) with a bandwidth of 0.075 and a Gaussian kernel. The shaded regions around each curve represent corresponding uncertainties, which are standard deviations of 100 bootstrap samples.
