Deflection angle of the plane of the Hyades stream for different pattern speeds of the Galactic bar w.r.t. the plane of the stream without a bar. The red triangle highlights the deflection angle for a bar having Ω_b = 39 km s⁻¹ kpc⁻¹, and the green vertical line corresponds to Ω_b = 55 km s⁻¹ kpc⁻¹. The dashed vertical black line indicates the pattern speed for which the guiding radius of the Hyades cluster will be located at the co-rotation radius (Ω_b ≈ 29 km s⁻¹ kpc⁻¹). The orange line shows the angle in the absence of bar (set to 0° by definition).
