Average stellar density of F8V-G5V stars from available SDSS data as a function of the cylindrical coordinates R (kpc), φ (deg.), z (kpc) for the range 0 <R< 30 kpc, | z | < 15 kpc, constrained within Galactic latitudes 8° ≤ | b | ≤ 22°. The circle stands for R = 8 kpc and z = 0 (like the Sun position) for any value of φ (for the Sun, it would be φ = 0). The axes in the bottom left panel apply to all panels in the figure.
