Fig. 13


Model vertical scale-heights for different mono-abundance subpopulations as a function of position in the [Fe/H]–[O/Fe] plane. Very good fits are obtained by using single exponentials, excluding the 200 pc closest to the disk plane. A radial range of 6 < r < 10 kpc similar to the SEGUE data is used. This figure can be directly compared with Fig. 4 by Bovy et al. (2012b). Our model predicts scale-heights of up to ~1.9 kpc for the oldest, most metal-poor samples; this should be compared to a maximum of ~1 kpc inferred from the Bovy et al. mass-corrected SEGUE G-dwarf data.
