LMC membership and population selection. Left panel: Infrared CMD from the VMC survey of the high-probability LMC member stars according to the 3D Jeans model fit. Right panel: Infrared CMD of the high-probability contaminant sources (foreground Milky Way stars and background galaxies) according to the 3D Jeans model fit. The inlet shows their spatial distribution in the VMC footprint. The dashed line is the same in both panels. It is used to separate the old and young LMC stellar populations.
