Contribution of the disc and halo components to the maximum velocity curve, i.e., local vertical peculiar velocity w = W − W0 (squared, km2 s−2) at the GP in terms of vertical eccentricity e′ (squared, dimensionless). The continuous lines correspond to the whole curve (black), the disc term (blue), and the halo term (red). The dashed blue and red lines are the respective tangent (TD) and asymptote (TH), the dashed grey line is their geometric mean, and the dashed green line marks the bound for the vertical speed (squared) of disc stars.
