Fig. 5.


Top row: surface density maps in lb of the model after the formation of the bar and b/p bulge. The metallicity range of each population is indicated at the top (from left to right we show the metal-rich, intermediate and metal-poor component respectively). Second row: fractional contribution maps of each population in the model. Third row: fractional maps of the MW bulge and inner disc from the APOGEE DR13 data. Fourth row: fractional maps of the model+DDF for each component. Bottom row: difference in fractional contribution between the model+DDF and the APOGEE DR13 data.
