Kinematic heliocentric distance (d) and projected Rayleigh statistic (V, Eq. (4)) for the 3° × 20° × 1.29 km s⁻¹ tiles. We report the largest (far) solution to the heliocentric distance equation, as detailed in Appendix B. From top to bottom, the panels correspond to each Galactic quadrant and to the whole Galactic longitude range. The colors indicate the Galactic longitude of the tiles. The horizontal dashed lines indicate V = ±2.87, which correspond to the 3σ significance in the preferential orientation around θ = 0° or θ = 90°, respectively. The solid line in the bottom panel corresponds to the mean V values in 1-kpc d_far bins.
