Selection function of bulge and disk field giants. Main panel: annotated CMD of a typical bulge field (003-03-C) is shown as a Hess diagram. The horizontal red dashed lines indicate the magnitude limits adopted to select cohorts, as described in the main text. Inset panel: μ_lcos(b) vs. μ_b VVV PM diagram. The black points correspond to a random 2500 field star subsample with small errors in PMs. The cyan (green) points in both panels display the kinematically selected bulge (disk) giants from the magnitude ranges displayed in the main panel.
