Comparison between the stellar density map of the central 86 pc × 20.2 pc of the Galaxy and the model. Upper: extinction-corrected stellar density map for stars with 9.0 ≤ K_s, extc ≤ 14.0. The dark regions are masked in the fit. Middle: Sérsic model for the NSC plus the background model (ID 10 in Table A.2). Lower: residual image given by the difference between the upper and middle panels divided by the uncertainty map of the density map. The color bar shown for the lower panel is in units of the standard deviation. The other two panels use the same linear color scale. Galactic north is up and Galactic east is to the left.
