The maximum rotational velocities (top; black squares) and the turnover radii (bottom; black circles) calculated from the rotation curves at each height. The values of the velocities are inclination-corrected, adopting an inclination angle of i = 89°. Horizontal errors indicate the range of heights (30 pixels, ∼8.2″ ≈ 0.4 kpc) binned along the slit direction. A bootstrap-with-replacement analysis is applied, and the best-fit results are shown as black dashed lines. The shaded blue regions mark the 1σ errors. The best-fit solutions show decreases in dV_m/dz of ∼ − 24.5 ± 15.5 km s⁻¹ kpc⁻¹ (below the disk or the southern half of the halo) and ∼ − 22.0 ± 14.3 km s⁻¹ kpc⁻¹ (above the disk or the northern half of the halo), and decreases in dR_t/dz of ∼ − 3.1 ± 2.9 kpc kpc⁻¹ (below the disk) and ∼ − 2.6 ± 1.1 kpc kpc⁻¹ (above the disk).
