Comparison of the orbital characteristics of stars of the Adibekyan et al. (2012) sample integrated in Model I (blue points) and Model II (red points) versus the Allen & Santillan (1991) model. From top-left to bottom-right: pericentres R_min, apocentres R_max, maximum vertical distance from the plane z_max, 2D eccentricities, period of vertical oscillations, and number of disc crossings are given. The insets in some plots show a larger range of values than that covered in the corresponding main plots. In all the plots, distances are in kpc, time in units of 10⁸ yr.
