Kinematic trends of the HARPS-GTO sample. The upper panels show the distribution of the sample in the v _X  − v _Y (or U V) and v _Y  − v _Z (V W) planes. We note that the 1σ errorbars are in most cases smaller than the symbols. The middle left panel shows the classic Toomre diagram (e.g. Feltzing et al. 2003), and the middle right panel shows a diagram of orbital heating (as measured by v _X and v − Z) as a function of age. The bottom panels display the orbital eccentricities and maximum heights above the Galactic plane, respectively, as a function of age.
