Rotation curve (top) and velocity dispersion profile (bottom) for our fields. A set of curves computed from the GIBS kinematical maps are displayed using colors corresponding to the latitude of each field. To split stars into metallicity components, we adopt values tuned in each MDF, as presented in Sect. 7; [M/H] = − 0.1 dex for p0m6 and p7m9, −0.2 dex for m1m10, and −0.5 dex for m10m8. Filled and open symbols represent component (i) and (ii). Triangle colored symbols stand for the respective complete field samples.
