Top panel: metallicity distribution for the EXT model (orange empty histogram) and for the Enceladus stream (blue filled histogram), and the globular clusters associated with it (vertical dashed lines. Bottom panel: Galactocentric distance vs. metallicity [M/H] for GAL (black filled dot) and EXT (red filled square) models, globular clusters in the MW disk (black empty dots; Harris 2010) and in the halo (pink stars; Dotter et al. 2010), potentially accreted clusters that might belong to Enceladus (red stars; Myeong et al. 2018), Sequoia (black stars; Myeong et al. 2019), the Sgr dwarf (blue stars; Bellazzini et al. 2003; Law & Majewski 2010), or the Canis Major (Cma) structure (green stars; Forbes & Bridges 2010), and MW dwarfs (red empty squares; Grebel et al. 2003).
