Point-source density maps of the VVVX surveyed regions in the outer bulge, showing sources detected down to K_s=16.0. Higher densities are shown with cooler colors, as indicated by the color bars on the right. Density increases toward the Galactic plane; note the different color bar ranges for the two panels. Darker points mark highly crowded stellar clusters. In the lower panel, the Sagittarius stream appears as a region of enhanced density near Galactic longitude l ∼ 5^°.5.
