FIGURE. 2.—The observed distributions of stars of different ages and metallisities in the Z coordinate relative to Sun: (a) young (t≤3 Gyr) metall-rich ([Fe/H]≤-0.13) stars; (b) young metal-poor ([Fe/H]<-0.13) stars; (c) old (t>3 Gyr) metal-rich stars, and (d) old metal-poor stars. Broken lines show five-point sliding-averadge smoothed trends within ±50 pc, and the dashed line shows an approximation of the histogram by a second-order polynomial over the interval from -50 to +30 pc. The arrows indicate the range over which the sample is complete. The double arrow indicates the position of the Galactic disk.
