Upper panel: SagDIG carbon stars highlighted on the proper-motion decontaminated m_F814W,(m_F606W − m_F814W) color–magnitude diagram. Members are displayed as squared crosses, while those of Galactic origin are shown as open square symbols. Lower left panel: Galactic foreground proper-motion decontaminated diagram, where the 3 crosses highlight the carbon stars with Galactic membership. Lower right panel shows a Trilegal simulation of the Galactic field along the SagDIG line of sight (thin/thick disk and Galactic halo are plotted as open squares, crosses, and dots, respectively).
