Number ratio of the bright AGB vs. RGB stars selected within the boxes described in Fig. 13 for a theoretical stellar population including two bursts (see legend) as a function of mass of the younger population. The shaded band encompasses the ratio of stars in our inner halo fields (W6, W9, W10, W11, and W12) counted in the boxes plotted with solid lines in Fig. 13. The horizontal line is the observed ratio when brighter stars are also included within the dashed box (22.25 < I₀ < 23.85) with respect to counts in the RGB box (23.85 < I₀ < 25.45).
