Left: continuum-subtracted [Fe ii] 1.64 μm channel maps of the DG Tau jet before (top panels) and after (bottom panels) deconvolution by the continuum image. The HV channel maps are integrated over the velocity intervals [–300, –160] km s^-1 (HVB) and [+120,+260] km s^-1 (HVR); the MV channel map over [–160, –50] km s^-1 (MVB) and [–50, +120] km s^-1 (MVR). The blueshifted lobe is at Δy <  0. The pixel scale is 005. A cross denotes the centroid of the continuum emission (shown as an insert in the top left panel). Contours start at 3σ and increase by factors of (lowest contours are 2.0 and 1.8 × 10^-18 W m^-2 arcsec^-2 in the raw HV and MV maps respectively). The solid red lines in the deconvolved maps show the opening angle measured in each component. Right: superposition of the deconvolved HV (background color image) and MV (yellow contours) channel maps. The stellar continuum is shown in red contours. The white cross locates the continuum centroid.
