Space velocities (V_R, V_ϕ and |V_Z|) for ∼66 000 field stars from our selected sample and 41 open clusters in the solar region. The data are presented in equally distributed bins (q = 14) for field stars (lime). In the background, the field stars are also shown on a density plot that is coded according to the black to white colour bar. The size of the symbols for clusters (blue circles) are proportional to the square root of their number of members (), shown in the legend with their total number of members. The straight lines represent the linear fits (green for field stars and blue for open clusters), and the curve (cyan) is a nonparametric LOWESS model to the clusters’ data.
