Extinction-corrected stellar number density map of the central 86 pc × 20.2 pc of the Galaxy for stars with 11.0 ≤ K_s ≤ 16.0 (9.0 ≤ K_s, extc ≤ 14.0). The magnitudes of individual stars were corrected for extinction using the extinction map of Dong et al. (2011). The dark patches in the image correspond to the green polygons in the extinction map (see Fig. 5). Sgr A* is located at the green star. Galactic north is up and Galactic east is to the left. The Galactic plane runs horizontally.
