Selection of the orbits of Fig. 16 with 10% parallax errors, but now with two cuts: σ_d ≤ 2 kpc and | Ω_r−⟨Ω_r⟩ | ≤ SD_Ωr. The colours are the same as in Fig. 17, with the addition that green points represent the particles that remain after the cuts. The grey vertical dashed lines indicate ⟨Ω_r⟩ and ⟨Ω_r⟩ ± SD_Ωr applied after the distance cut. The insets in the top panels show the number of remaining particles after the cuts N_cut, while those in the bottom panels are the number of particles within a distance of 20 kpc from the Sun N (d< 20 kpc).
