Parameters in the comparison of metallicity distributions [Fe/H] for different subsamples of LAMOST-DR3 giants with R1 < R < R1 + ΔR, |z| < 5 kpc, and R2 < R < R2 + ΔR, |z| ≥ 5 kpc, respectively, such that ⟨r1⟩≈⟨r2⟩.
Notes. Thefirst three columns indicate the Galactocentric radial range, Cols. 4 and 5 give the number of stars, Col. 6 gives the average signal-to-noise ratio of the first subsample, Col. 7 gives the average error of the [Fe/H] measurement in the first subsample, and Col. 8 gives the probability derived from a Kolmogorov-Smirnov test that the two metallicity distributions are identical within the random fluctuations. The distances are listed in kpc.
