Caption: Figure 4.

Color–magnitude diagrams of five 4.5 deg² fields in the PAndAS footprint. The locations of the fields are highlighted in the map displayed in the left-most panel, which reproduces Figure 3. All five fields have the same coverage and target regions of interest, as described in the text (see Section 3.3). A Dartmouth isochrone of age 10 Gyr, metallicity [Fe/H] = −1.5 (Dotter et al. 2007), and [α/Fe] = +0.2, shifted to a distance modulus of 16.2 (i.e., a distance of 17 kpc), is overlaid on the CMDs and shows a good match with the MS and MSTO of fields (a) and (c).
