[Na/Fe] and [Mg/Fe] abundance ratios of the Helmi stream stars (red symbols). Also plotted are halo stars from NS10 and R17, with Gaia-Enceladus stars shown with filled symbols. G112-43 and G112-44 from NS10 are shown with red stars since their kinematics are consistent with the Helmi streams. We also show kinematically selected Sequoia stars from Paper I.
