Moment 0 maps of the C¹⁸O emission integrated over four different velocity ranges, high velocities (V_LSR = 2.9–3.8 and 10.3–11.4 km s^-1), medium-high velocities (V_LSR = 3.8–4.8 and 9.2–10.3 km s^-1), medium-low velocities (V_LSR = 4.8–5.8 and 8.2–9.2 km s^-1), and low velocities (V_LSR = 5.8–7.1 and 7.1–8.2 km s^-1). Blue and red contours present the blue- and redshifted emission, respectively. Blue and red arrows show the directions of the blue- and redshifted outflows. Crosses denote the position of HL Tau. Filled blue ellipses show the size of the synthesized beam. Contour levels are 5σ, 10σ, and 15σ in the high-velocity blueshifted map, are 5σ, 15σ, 30σ, 50σ, and 70σ in the high-velocity redshifted map, are 5σ, 15σ, 30σ, and 45σ in the medium-high-velocity maps, are 5σ, 10σ, 15σ, 25σ, 45σ, and 75σ in the medium-low-velocity maps, and are 5σ, 10σ, 15σ, 25σ, 45σ, and 75σ in the low-velocity maps. The noise level in the high-velocity redshifted map is 5.1 mJy Beam^-1 km s^-1, and the levels in the other maps are all 3.9 mJy Beam^-1 km s^-1.
