Energy-angular momentum structure of the MW bulge components identified using 2D GMM in the [Fe/H]–[Mg/Fe] plane. The top panels are the same as in Fig. 17 and are given for reference. The bottom group of panels show the normalised stellar mass for the entire component (top) and the region inside (middle) and outside (bottom) the bar. The numbers in the middle and bottom rows correspond to the mass fraction of a given component inside and outside the bar. The white dashed lines mark the minimum possible energy for a given value of the angular momentum.
