Equatorial map showing the position of all the fields used in this work and the closest cold stellar overdensities to them. These overdensities are used for comparison and discussion of the stellar density profile data-to-model residuals throughout Sect. 4.3. The labels in the figure correspond to the Anticentre Structure (ACS), the Eastern Band Structure (EBS), the NGC 5466 stream, the Grillmair & Dionatos stream (G&D), the Orphan stream, the Triangulum-Andromeda overdensity (Tri-And) and the Pisces overdensity. The background image is the SDSS-DR8 map from Koposov et al. (2012), which shows the footprint of the Sagittarius stream. The Monoceros ring also appears partially in this background image, as a dark region overlapping the western part of the Galactic disk in the anticentre region, eastwards of the ACS.
