Deconvolved image of the DO Tau receding (left) and approaching (right) jet in Fe II 1.64 μm line, integrated over v_LSR = [−122, 228] km s⁻¹. The contour floor is 3σ increasing inlog intervals of 0.5 (where 1σ is 1.43  × 10⁻¹⁸ erg s⁻¹ cm² Å. The derivedjet axis position is overlaid in black dots with associated error bars. Rotating to the horizontal yields a blue-shifted jet position angle, PA_jet = 260°. Blue and redcontours trace C¹⁸O emission integrated over v_LSR = [4.21, 5.01] km s⁻¹ and v_LSR = [7.01, 7.61] km s⁻¹ respectively. The contour floor is 3 σ (13 mJy beam⁻¹), increasing inlinear intervals of 1 σ (4.5 mJy beam⁻¹).
