CMDs of Galactic bulge regions for VVV representative fields at the uppermost (left panels, at VVV field b201, centered at l = 350°̣75, b = −9°̣69 in the outer bulge) and lowermost (right panels, at VVV field b319, centered at l = 359°̣49, b = −0°̣95 in the inner bulge) latitudes available to the VVV observations. The upper panels represent the ZKs vs Ks CMDs, while the middle panels represent the JKs vs Ks CMDs build from our PSF photometry. Darker colors represent higher densities of sources. In the lower panels, synthetic CMDs built using Besançon Galactic model (Robin et al. 2003). In the outer bulge CMD we are able to separate the different sequences of stellar populations mentioned in the text. In the inner bulge CMDs those sequences are significantly blurred out due to differential extinction, but some overdensities from the bulge RGB manifest clearly as described in the text. A series of online movies show the CMDs for the different VVV bulge fields.
