StarHorse posterior Gaia EDR3 CMDs. Top row, from left to right: all converged objects (362M), Gaia EDR3 cleaned sample (321M), EDR3- and flag-cleaned sample (282M). Middle row: CMDs for three broad magnitude bins, showing both the increasing mix of stellar populations (e.g. the giant-star populations of the Magellanic Cloud starting to appear around M_G ∼ −3 in the 16 < G < 17 panel) and the decreasing astrometric quality with increasing magnitude. Bottom row: separate CMDs for the Milky Way disc (left; 339M stars), the LMC (middle; 1.09M stars), and the SMC (right; 94k stars). The abrupt absolute magnitude cut in the last two panels is caused by the G < 18.5 mag cut.
