CMD of all stars within PAndAS, excluding masked regions near M31, M33, NGC 147, and NGC 185. Pixels have a size of 0.02 mag in both the color and magnitude directions. Stellar structures at different distances in the MW halo are responsible for the hook-like features visible within the color range 0.2 ≲ (g − i)₀ ≲ 1.0. Stars from the M31 stellar halo produce the dense structures in the faint and red parts of the CMD. The same binned CMD is shown on the three panels, but the MS and MSTO tracks of the features mentioned in the text, along with the region dominated by M31 stars, are overlaid on the middle panel. These are directly taken from Martin et al. (2007b). The MS-tailored selection boxes used to build the maps of Figure 2 are overlaid in the right-most panel.
