Rotational velocity profiles for the MW’s disks. The gray points in the left and central panels are the stars with |z|< 1 kpc and |v_ϕ|< 350 km s⁻¹, which were used to construct the inner v_ϕ profile. The light blue and orange points in the left and central panels, respectively, are the thin- and thick-disk stars selected in the (j_z/j_c,[O/Fe]) space. The parameters of the two fits in the right panel are given in Table 3. For the thick disk, only the region R < 13 kpc was considered for the fit.
