Fig. 8


Azimuthal velocity component Vφ as a function of the Galactocentric radius RGC. Colors as in Fig. 2. For each GMM data family, a central tendency curve is constructed by separating the dataset into a number of equally populated bins in RGC. Median values inside each bin determine the position of the dots in the curves. Only stars with 5 <RGC< 10 kpc are considered to avoid undersampled bins in the extremes of the distribution. Error bands are computed at the 1σ and 2σ level by Monte Carlo resamplings to take into account the effect of errors in metallicity and abundances on the sample classification.
