Figure 19.
The metallicity distribution of all Milky Way field stars observed with GIRAFFE in the Gaia-ESO Survey iDR4. (a, c) and (b, d) show metallicity distribution of stars within blue and red boxes, respectively. The blue and red lines show the observed metallicity; the black dashed lines show weighted metallicity distributions. Only stars with [Fe/H] < 0.50 are included.
