Same as Fig. 2 but for different distance intervals shown from the closest (top panel of left column) to the most distant (bottom panel of right column). The distance ranges adopted in each panel are indicated in their lower right corner together with the number of stars in their bottom left corner. The colour code corresponds to the median of the metallicity and is continuous between the first four subpanels showing rather metal-rich stars, and the two last panels dominated by metal-poor populations.
