Columns 2-4 list the U, V and W velocities relative to the local standard of rest (LSR). Columns 5-7 list the Gaussian distributions of each population: thin disc, thick disc, and halo, respectively. In Cols. 8 and 9, we provide the relative probabilities of the thick disc relative to the thin disc and of the thick disc relative to the halo. The last column depicts the probable population where each star belongs.
