Fig. 9


Binned color−magnitude and color−color diagrams for all sources defined as stellar in the VVV catalogues (86 millions), which constitutes 152 tiles of the Galactic disk. Magnitudes have been transformed to the 2MASS photometric system in each tile using the respective coefficients. The CMD has been calculated at a resolution of 500 × 1600 bins, which corresponds to a binsize of 0.005 mags/bin. Similarly, our color−color diagram for the tiles of the Galactic disk was constructed at a resolution of 400 × 800 bins and the same binsize of the binned CMD. The latter includes an unreddened 0.05 Gyr isochrone (grey solid line) in the 2MASS system for reference.
