Notes. ⟨ VGC ⟩ is the mean galactocentric radial velocity and σr the radial velocity dispersion. The distance to the Sun corresponds to the mode of the distance distribution function. σdist corresponds to the 68% HDI of the distribution (see Sect. 5.3). The errors are computed using bootstrap resampling.
