Vertical velocity (V_z, SMC), radial velocity (V_r, SMC), and azimuthal velocity (V_ϕ, SMC) vs. metallicity of the stars in the six targeted MC substructures along with stars targeted by APOGEE-2 in the central SMC. The velocities were calculated with respect to the assumed SMC disk plane, as described in Sect. 2, using an assumed distance of 60 kpc and using the formalism and best-fit model parameters presented in Zivick et al. (2021).
