Fractional number of stars for thick disc and YAR samples in different mean radii ranges.
| N0 − 6/N6 − 9 | N6 − 9/N9 − 20 | |

Notes. The second column represents the fraction of star within 6 kpc from the galactic centre over the stars in the range 6–9 kpc. The third column show the analogous quantity but for 6–9 kpc and 9–20 kpc ranges. The fraction can be minimised or maximised (min and max) taking into account the Poisson uncertainties of N0 − 6, N6 − 9, and N9−20.
